1, the safe period of contraception method of the claim in the end where it came from? I searched the foreign uptodate database, it turns out that in some special religious beliefs, women are prohibited from using any form of contraception, they can only determine the day of ovulation and conception by daily observation of vaginal discharge and measurement of basal body temperature, and the nature of vaginal discharge is vulnerable to sex and vaginal inflammation, so the probability of failure of this method of contraception is about 25%, that is, 1 in 4 This means that 1 out of 4 women will have an unwanted pregnancy. Do you think it’s dangerous? 2, then why my husband and I have had children for 5 years, are using the safe period contraception method, never had an accident! For 5 years, if your menstrual cycle is not particularly regular and you can accurately apply secretions and temperature to determine the conception period, then you should go to the reproductive department next door. 3, that I am 20 years old, menstrual cycle is not very regular, and also with a strong boyfriend two safe period contraception have been successful ah! This is a gamble of luck, you can guarantee that your luck will be so good next time? 4, that I just used a safe period contraception method, should I take the emergency contraceptive pill ah? My advice is very clear: to eat! Because the biggest impact of the emergency contraceptive pill on the body is the transient menstrual disorders, will soon recover, and once the risk of accidental pregnancy, to do abortion on the body can be said to be several times the damage of the emergency contraceptive pill. In addition, there are people worried about the emergency contraceptive pill will lead to infertility, in fact, not, the development of assisted reproductive technology for so many years, see the most is the abortion of the damage caused by infertility, take the emergency contraceptive pill can be said to be 0. And unlike the previous 72 hours to take, the international has updated the recommendation: unprotected sex within 5 days after the emergency contraceptive pill can be taken. So take the emergency contraceptive pill this thing, simply do not have to entangle. 5, after unprotected sex just do not want to eat, do not want to take the emergency contraceptive pill! Is there any other method? There is also a way to do ultrasound monitoring of ovulation every day, remember, it is every day, if the monitoring of the discharge of follicles within 5 days after sex, in order to avoid unwanted pregnancy do not hesitate.
