All parents want to have a healthy and smart baby, but they don’t always get what they want. Many couples may go into a “minefield” when conceiving if they are not careful. The following is an introduction to you. 1, conception soon after stopping the contraceptive pill It is currently believed that conception in the case of too short a time after stopping the contraceptive pill, there is a possibility of deformed children. Because, oral contraceptives for hormonal drugs, the role of many times stronger than natural sex hormones, such as No. 1 short-acting contraceptives, which contains ethinyl estradiol physiological effects, is the body produced by the 10-20 times of the enestradiol; contains the physiological effects of ethinyl estradiol, is the body produced by the progesterone 4-8 times. Moreover, since oral contraceptives enter the body through the intestine and are metabolized and stored in the liver. If the discontinuation time is too short, the contraceptive pill in the body cannot be completely excreted, which may cause certain defects to occur in the embryo. Avoidance method: It is best to stop taking oral contraceptives 6 months before the planned time of pregnancy to allow the residual contraceptive pills in the body to be completely excreted. During this period, you can use non-drug methods of contraception, such as the use of condoms. 2, conceive while traveling Some couples get pregnant accidentally while traveling, and some of them continue the pregnancy. This is not a good practice, because during the trip the couple will be overly exhausted, coupled with irregular life, often sleep deprivation, three meals a day nutrition is also prone to imbalance. As a result, not only will the quality of fertilized eggs be affected, but also reflexively cause uterine contractions, so that the embryo’s implantation and growth will also be affected, leading to miscarriage or pre-eclampsia. Some data reported that about 20% of women who became pregnant while traveling had a pre-eclampsia or early miscarriage, and 10% developed secondary infertility later. Avoidance method: Even during travel, attention should be paid to the use of contraceptive measures, so as not to accidentally conceive and bear the “bitter fruit”. 3, ectopic pregnancy soon after conception The onset of ectopic pregnancy is very critical, but after timely and effective treatment many people can still carry a baby. However, some women are so eager to have children that they often rush to get pregnant again soon after the cure. This is dangerous because the fallopian tubes may not be completely unblocked. Information shows that the incidence of repeat ectopic pregnancy is about 15%. Avoidance method: If an ectopic pregnancy has occurred, you must insist on contraception for a period of time after complete cure and consider pregnancy only after the doctor’s examination that everything is normal so as not to trigger another dangerous ectopic pregnancy. 4. conceive soon after cesarean section Some women had a cesarean section during their first child for various reasons. If the child does not survive, some of them will soon become pregnant again, which is not good for their health. This is because more blood is lost during a cesarean section than during a normal delivery, and all organs need to be repaired after delivery. Therefore, it takes time for both the uterine and abdominal incisions to heal adequately after a cesarean section. Any factor that interferes with the muscularization of the uterine scar can cause different degrees of defects in the scar. If it does not grow strong, it is prone to perforation or even rupture when conceiving again. Avoidance method: Generally speaking, women who have had a cesarean section should have another baby at least 2 years later to give the uterus time to heal adequately so that the scar tissue heals a little better and reduce the risk of another delivery.
