What Are the Signs of Pregnancy Before a Missed Period?

The combination of sperm and egg is called conception or fertilization. The conception process is as follows: During sexual intercourse, the man injects semen into the woman's vagina, and the sperm relies on the tail to swing toward the uterus and then enter the fallopian tube.

The environment is the foundation of everything. For the sake of the future baby's health, creating an optimal conception environment is the highest priority.

There are many ways to achieve fertility and fertility. One of them is to calculate the ovulation day. We know that the chance of conception is high on the day of ovulation, and the quality of fertilization is also good. Female friends with normal menstrual cycles generally start ovulation on the 14th day before menstruation. The egg's survival time is only twelve to twenty-four hours, and the sperm survival time can reach seventy-two hours. Therefore, the calculated ovulation Arranging the same room three days before and after the day will make pregnancy easier.

Eight conditions a child must conceive:

1.Conceive while using contraceptives

Some couples conceive unexpectedly because of failure to use contraceptives, but many continue to conceive with luck. You should know that whether you take a contraceptive pill or a topical contraceptive film, once you become pregnant, it will adversely affect the fertilized eggs. The data show that children born of failed birth control pills have a higher chance of developing congenital malformations, and their maturity, weight, and growth rate at birth are also significantly different from those of normal pregnant children.

2.Conceive with a contraceptive ring

If the contraceptive ring is not suitable or is displaced in the uterine cavity, pregnancy with a ring is prone to occur, the probability is about 10%. The contraceptive ring is placed in the womb as a foreign body and interferes with the implantation of the fertilized egg to play a contraceptive role. But no matter how long the ring is released, it will cause more or less damage to the endometrium, which is very unfavorable for the growth and development of the embryo or fetus.

3.Conceived shortly after cesarean section

Some women had a cesarean section for a variety of reasons during their first child. If your child fails to survive, some of them will soon become pregnant again, which is bad for your health. Because blood loss during cesarean section is more than during normal delivery, all organs need to be repaired after delivery. Therefore, whether it is a uterine or abdominal incision after cesarean section, full healing takes a certain amount of time. Any factors that interfere with the muscleization of uterine scars can cause scars to have varying degrees of defects. If it is not long and sturdy, perforation or even rupture is easy to occur during pregnancy.

4.Conceived shortly after preterm or abortion

For women who have had premature or miscarriage, their endocrine functions have not been fully recovered, and genitals such as the uterus have not recovered, especially women who have undergone curettage. If the body is conceived quickly, it will not provide a good growth environment for the fetus, and it will not help the uterus to return to normal.

5.Conceived shortly after ectopic pregnancy

Ectopic pregnancy is very critical, but many people can still conceive a baby after timely and effective treatment. However, some women are eager to seek a child and often rush into pregnancy shortly after being cured. As everyone knows, this approach is very dangerous, because the fallopian tubes may not be completely cleared. Data show that the recurrence rate of ectopic pregnancy is about 15%.

6. Get pregnant soon after stopping taking the pill

At present, it is believed that when the pregnancy is stopped for a short time after the contraceptive pill is stopped, there may be deformed children. Because oral contraceptives are hormonal drugs, their effects are many times stronger than natural sex hormones. For example, the short-acting contraceptive No. 1 contains physiological effects of ethinylestradiol that is 10-20 of diestradiol produced in the body The physiological effect of norethisterone is 4-8 times that of progesterone produced in the body. Moreover, since oral contraceptives enter the body through the intestine, they are metabolized and stored in the liver. If the withdrawal time is too short, the contraceptives in the body cannot be completely discharged, which may cause some defects in the embryo.

7. Less than 3 months of rubella vaccine

Once pregnant, once infected with rubella virus, it may cause congenital malformation of the fetus. To avoid rubella virus infection during pregnancy, the most reliable method is to inject rubella vaccine before pregnancy. However, the injection should not be performed within 3 months after the vaccine injection or after pregnancy, or the virus in the vaccine will directly affect the fetus and cause developmental abnormalities.

8.Conceive while traveling

Some couples get pregnant unexpectedly while traveling, and some continue to get pregnant. This approach is not appropriate because some couples are physically exhausted during the journey, their daily lives are irregular, and they often lack sleep. Therefore, it may affect the quality of the fertilized eggs, and also cause the uterine contraction to reflect, so that the implantation and growth of the embryo are also affected, which may easily lead to abortion or threatened abortion. It is reported that about 20% of women who are pregnant during travel have a threatened abortion or early abortion, so you should be careful during pregnancy.

Having a healthy child is what every family of childbearing age wants. In the above 8 cases, the baby is likely to be unhealthy. Preparing couples should take precautions. ^[2]
