How to avoid pregnancy after having sex

Female friends who have not yet made good preparations for having a baby ignore contraception during intercourse, which will increase the risk of pregnancy. Therefore, female friends in this situation are most worried about unexpected pregnancy. So, how can you not get pregnant after having sex?

1. Women who have had sex without taking any contraceptive measures should take preventive measures immediately to prevent unwanted pregnancy. The most common method is oral contraceptive pills, which can prevent the embryo from implanting and thus reduce the risk of accidental pregnancy in the future.

2. Women should pay attention when using this type of medicine. The use of contraceptive pills also has a specific scope of application. It needs to be taken within 72 hours after intercourse and must be taken under the guidance of a doctor. Because some women may have strong allergies to this type of drug due to physical reasons, in order to avoid the risk of drug allergy, only by using the drug according to the doctor's advice can the purpose of relatively reliable post-contraception be achieved.

3. In addition, women who take this kind of contraceptive pills should also pay attention to their normal menarche time. If they find that the previous menstrual period is delayed, they should also consider whether there is a reason for the failure of subsequent contraception and go to the hospital's gynecology department for a follow-up visit in time.

How long does it take to get pregnant after sex

How long does it take to get pregnant after having sex? After having sex during the ovulation period, the sperm and egg combine closely. Generally, if you do not have your period 14 days after the ovulation period, you are pregnant. Gynecologists say that generally, after the sperm and egg combine and stay in the fallopian tubes for 3-5 days, the embryo will implant in the uterine wall. Under normal circumstances, it takes 6-8 days for the embryo to implant. If you have sex after ovulation, you can go to the hospital for blood tests and B-ultrasound tests about 7 days after your period to confirm whether you are pregnant for the most accurate reason. You can also have a blood test after the embryo has implanted to confirm it. Some are earlier, some are later, and some are very different. It is best to buy a pregnancy test strip and test it in about a week. Morulas are produced 3-4 days after fertilization, and embryos are produced 6-8 days after fertilization. Embryo implantation begins 6-8 days after fertilization and is complete on 11-12 days.

After entering the woman's vagina, male sperm can survive for 2 to 3 days. If it encounters ovulation during this period, pregnancy will occur. The lifespan of an egg cell is about 2-3 days, while it takes one day for male sperm to travel from the vagina to both fallopian tubes, and two days for the embryo to implant. Therefore, the time it takes for a couple to get pregnant after sexual intercourse should be 2 1=3 days. In medicine, the time of pregnancy is generally calculated from the first day of the expected date of delivery. If you do an ultrasound, generally speaking you can see it in 25 to 38 days, but for some women, due to late fertilization and late implantation, it may take about 40 days to see it. Therefore, the latest period will not exceed 40 days.
