As an excellent technology, in vitro fertilization (IVF) is the best way to deal with various stubborn infertility. Through the process of in vitro fertilization and cultivation, IVF technology can cleverly avoid various risk factors that affect pregnancy. But in vitro technology also makes many people feel uneasy, especially because there are no necessary hormone stimulating factors in the process of in vitro technology, which makes embryo transfer very difficult. Even after successful embryo implantation, there may be unstable pregnancy and easy miscarriage. So how many months did in vitro pregnancy begin to stabilize? How long is the stable time for in vitro pregnancy?

1、 Why is IVF pregnancy unstable?

The rate of chromosomal abnormalities in elderly patients is much higher than that in young people. Chromosome abnormalities are an important factor in miscarriage, and elderly women have a higher miscarriage rate. The older they age, the more likely they are to miscarry. If the quality of the embryo itself is poor, it will naturally be eliminated. The quality of an embryo directly depends on the egg and sperm. If the quality of sperm or eggs is poor, it is easy to miscarry. Multiple pregnancies in IVF are higher than natural pregnancies, and multiple pregnancies can easily lead to miscarriage. Many patients want to conceive twins, but the uterine environment is not good enough, leading to miscarriage. Therefore, it is not recommended for elderly or physically ill women to conceive twins. Any spouse who has chromosomal abnormalities, has given birth to a defective baby, or has a family genetic disease will have an early miscarriage. For these issues, third-generation in vitro technology is needed to solve, and chromosome screening cannot be performed on the first and second generations. Mentality is also crucial. After all, test tubes cannot reach 100%. During transplantation, it is important to maintain a calm mindset and avoid nervousness and fear, as this can also stimulate uterine contractions and lead to miscarriage.

2、 How many months did in vitro pregnancy begin to stabilize?

Usually, the stability of in vitro fertilization is basically the same as that of natural pregnancy, and it can only become more stable after 3 months of pregnancy. Generally speaking, it is recommended for women to rest appropriately after embryo transfer, and if necessary, to rest in bed for a period of time. After embryo transfer, a period of luteal support treatment is required, lasting for about 8-10 weeks. It is best to check whether the embryo transfer is successful about two weeks after implantation. In order to improve the quality of oocytes and prevent fetal neural tube malformations, folic acid can be taken in early pregnancy and early pregnancy under the guidance of a doctor. After successful in vitro fertilization embryo transfer, similar to natural pregnancy, regular prenatal examinations are sufficient. Before IVF, both men and women need a physical examination. If the female has abnormal sexual/thyroid hormones, it requires 1-2 months of pre-treatment. If everything is normal, it usually takes about 2-3 months for IVF testing to complete.

3、 What to do if IVF is unstable?

After embryo transfer, the embryo needs to be implanted into the uterine cavity. However, due to treatment such as ovulation induction in the pre test tube stage, the luteal function of the female corpus luteum is affected. Therefore, after embryo transfer, it is necessary to supplement progesterone and estrogen to promote embryo implantation. Commonly used drugs include progesterone injection, progesterone tablets, human chorionic gonadotropin, and estradiol valerate. Within 2 hours after embryo transfer, the doctor will arrange suitable medication for abortion treatment. Be sure to remember clearly. If you don't know, ask the nurse promptly and insist on timely treatment every day. Don't stop taking medication hastily, otherwise it may cause bleeding. 14 days after transplantation, go to the hospital on an empty stomach to draw blood and measure serum HCG, which is generally greater than 50Miu/ml, indicating pregnancy. Continue abortion treatment for 14 to 21 days and undergo ultrasound examination. If a gestational sac with fetal buds and pulsating fetal heart is seen in the uterus, clinical pregnancy can be determined. Abortion treatment generally needs to be maintained until 55 days after embryo transfer, and can only gradually alleviate after the condition stabilizes. In terms of diet, there can be no significant time difference. You can eat more fresh fruits and vegetables, as well as foods rich in protein, such as milk, eggs, and lean meat. In terms of lifestyle, as long as you don't feel tired, you can continue working and doing household chores. There's no need to lie down for a few months! It is best not to have sexual intercourse or engage in vigorous exercise during the first three months of pregnancy. During abortion treatment, peace of mind is the most important. Relax, maintain a good and peaceful attitude, and don't be nervous. Excessive anxiety is not conducive to pregnancy, it can only lead to endocrine abnormalities and is not conducive to pregnancy.

Overall, it is relatively safe to use test tubes now. As long as you follow medical advice and do not do anything high-risk, it is generally possible to successfully give birth. Compared to in vitro fertilization, natural reproduction actually has no disadvantage in terms of success rate. Due to the use of progesterone, the success rate may be even higher!
