How does accidental pregnancy occur and what conditions can lead to accidental pregnancy

Why did you get pregnant unexpectedly? In current life, it is believed that some couples may suddenly discover an unexpected pregnancy during a period when they do not want to have children, and the reason for this is unknown to themselves. So why did they unexpectedly become pregnant? Let me introduce it to you.

Analyzing the Causes of Unexpected Pregnancy

Recently, the contraceptive pill "short weight and short weight" has been recalled due to the risk of contraceptive failure. Think about it, even if you take contraceptive measures, you may still get pregnant. This kind of accident is really an accident in an accident.

"Unexpected pregnancy" and "contraceptive failure" have become many "Cheng Yaojin" who disrupt marriage plans. How can you still be caught if you have contraception? Experts point out that sometimes the reason for contraceptive failure is due to the lack of contraception at all, and sometimes it is because the contraceptive measures taken have gone wrong.

Reason 1: Safe period contraception is not reliable

Safe period contraception is the least safe method of contraception! Many people have mistakenly chosen safe period contraception and have been recruited. "Chief Physician Zhou Longshu, Director of Obstetrics and Gynecology at the Second Affiliated Hospital of Guangzhou Medical College, pointed out to the New Express reporter that it is difficult to estimate the ovulation time of women, and some women have inaccurate menstrual cycles, making it very difficult to calculate safe period. Even for people with regular menstruation, ovulation may not be as regular as menstruation, and may be advanced or delayed. Sexual excitement may also lead to premature ovulation, "Zhou Longshu said.

Some people pay attention to feelings and do not take contraceptive measures, but use extracorporeal ejaculation as a so-called "contraceptive method", which is also an unsafe contraceptive method. This contraceptive method is too unsafe, and it is often difficult to grasp the timing of ejaculation when there is high tension. Moreover, people who use extracorporeal ejaculation are mostly young, and their control ability is usually poor. "Zhou Longshu said that any leakage of semen in the woman's body can lead to unintended pregnancy, which is also equivalent to not using contraception.

Improper use of condoms is equivalent to no contraception, "experts say. The correct way to use condoms is to wear them before sexual intercourse, but some people only wear them before ejaculation to feel better, and the result is similar to external ejaculation.

Reason 2: Contraceptive device displacement and expiration

How can you still get pregnant after getting an IUD?! "Xiao Xiao asked the doctor puzzled. Because she had already given birth to a child, Xiao Xiao went to the hospital for an IUD after giving birth. She thought it was safe and secure, but unexpectedly, she was still "recruited". After taking her ultrasound, the doctor found that her contraceptive ring had been displaced to the cervix! This is the reason why she failed to use contraception despite getting an IUD.

Zhou Longshu told reporters that generally speaking, IUD is a better and higher contraceptive method, with a low failure rate, but there are also very few cases of contraceptive failure. Some people have a lot of menstrual flow after getting an intrauterine device (IUD), and if the contraceptive metal ring is moved to the cervix or other places during menstruation, it will not have a contraceptive effect. He said that the IUD should be placed in the uterine cavity to prevent the implantation of fertilized eggs. However, there are different sizes of contraceptive rings: small, medium, and large. Everyone should choose a suitable size based on the size and depth of the uterine cavity. If not selected properly, it can easily cause the contraceptive ring to shift and not have a contraceptive effect.

Another possibility is that the contraceptive ring has passed its expiration date, but you are still pregnant after getting an IUD, "he told reporters. Currently, most contraceptive rings have a validity period of 5 years, and some with medication have expired, and the drug components are basically released, resulting in a decrease in contraceptive effectiveness. If not replaced in a timely manner, contraception will fail.

Reason 3: Short acting contraceptive pills are damp

Xiao Qian, who works in an advertising company, is usually very busy with her work. Not long ago, her group just passed a proposal, and after the proposal was approved, everyone ate together to celebrate. This celebration lasted all night again. Xiao Qian, who had been struggling with proposals for a few days, fell asleep in bed as soon as she got home, not even taking the contraceptive pills she had to take every day. The next day, Xiaoqian, who was in a good mood after taking compensatory leave at home, and her husband warmed up for a while, but she didn't think of taking one less day of contraceptive pills. At night, when she saw the contraceptive pills on the dressing cabinet, she suddenly remembered about missing them. As expected, the cost of missing one dose was that she discovered pregnancy one month later.

Short acting birth control pills need to be taken daily according to a cycle. For a continuous period of time, we have found that if one dose is missed during the use process, it is easy to get caught! "Zhou Longshu pointed out that short acting birth control pills can be seen as a daily dose of only one day, so missing a dose can easily lead to" accidents ". Generally speaking, short acting birth control pills must be taken from the 5th day of menstruation, with one pill taken every night and 22 consecutive pills taken without interruption. In case of missed medication, one tablet should be taken within 12 hours.

Another possibility is that the short-acting contraceptive pill has failed, with reasons for failure including expiration or dampness. Most people do not know that the contraceptive pill will fail if it becomes damp. Many birth control pills are coated with a layer of sugar coating, which is different from the sugar coating of general drugs. The sugar coating on the outside of general drugs is wrapped for a good taste, while the sugar coating on the outside of short-term birth control pills itself contains drug components. Experts say that after getting damp, the sugar coating dissolves, causing the drug components to fall off, and if taken in vain, contraception will fail.

Reason 4: Mixed administration of antibiotics reduces efficacy

Xiao Zhang shyly took his girlfriend to the hospital for an abortion. Because of a close relationship between the two, their girlfriend unexpectedly became pregnant. The depressed girlfriend whispered to the doctor that after the two became unprepared intimate, she took the emergency contraceptive pill, but suspected it was fake. The attentive doctor noticed that Xiaozhang's girlfriend was clamping her teeth and asked, "Did you take anti-inflammatory drugs during that time?" Xiaozhang's girlfriend said in surprise, "Yes, during that time, her teeth became inflamed and she took anti-inflammatory drugs for a period of time." It turned out that this contraceptive failure may also be related to her taking anti-inflammatory drugs.

Within 72 hours, the earlier the better. "This is expert advice on taking emergency contraceptives. Some people mistakenly believe that emergency birth control pills can control sexual activity within 72 hours, but if they engage in sexual activity again after taking them without taking contraceptive measures, it can lead to contraceptive failure, which is more common among young people. "Zhou Longshu said that if the fertilized egg has already been implanted or has arrived in the uterine cavity, taking emergency birth control pills will have poor contraceptive effects.

In addition, for some special populations, taking emergency contraceptive pills for contraception may have poor effectiveness. If taking anti-inflammatory drugs such as sulfonamides, erythromycin, and cephalosporins, it can affect the absorption of emergency contraceptives, "experts said.

How to avoid accidental pregnancy?

1. Men can use male condoms;

2. Women can use oral contraceptive pills, contraceptive injection needles, uterine rings, uterine caps, female condoms, topical contraceptives, or ovulation prediction methods.

3. For those who have decided not to have children again, permanent contraception methods such as male or female tubal ligation can be used.

4. If no contraceptive method is used during sexual intercourse, or if contraception fails, post coital contraception can be used to avoid unintended pregnancy - that is, taking emergency contraceptive pills within 72 hours after sexual intercourse or wearing a uterine ring within five days after sexual intercourse. However, both require consultation with a doctor before use.

What should I pay attention to for contraception?

To reduce the chance of accidental pregnancy, it is best to consult a doctor before choosing a contraceptive method, undergo a physical examination, and follow the doctor's instructions to use a contraceptive method that is suitable for one's physical condition and effective. The effectiveness of each contraceptive method will be affected by factors such as individual physical condition, past illness, childbirth, or changes in lifestyle habits. So women who engage in sexual activity, whether unmarried or married, should undergo regular physical examinations to determine if there is a need to switch to other contraceptive methods.

Why did you get pregnant unexpectedly? The above editor has already introduced to you, and I believe you have a certain understanding of why accidental pregnancy occurs. In fact, whether couples or couples, as long as they know contraceptive methods, they can avoid accidental pregnancy, which is the way of love.
