First, in the early stage of IVF, all injections of some medications are required for down regulation. Some people are not sensitive to the drugs or cannot achieve the expected goal of down regulation due to various factors such as after partial ovarian removal, ovarian hypofunction, polycystic ovaries, etc., and need to choose a new drug regimen. In this case, it is a waste of time and money, but there is no way out, because each person’s response may be different due to the psychological blow. Second, after successful down regulation, medications are applied to promote follicle development. When multiple follicles are >=18 mm in diameter, the eggs are retrieved within 36 hours after using another drug. In some cases, only 1-2 follicles develop after the use of ovulation medication, or for some reason, all the follicles have been eliminated and they do not know where they are going, so the doctor cannot find the follicles, and the process is half-hearted. Third, egg retrieval. During egg retrieval, the nurse will give the patient an intramuscular injection of pain relief such as Dulcolax, but most of the patients cannot eliminate the pain, but at most reduce it. Of course, if the doctor is highly skilled and light-handed, it will not hurt (as some people have proved), but not everyone can retrieve the eggs, and it is futile not to retrieve the eggs or to retrieve eggs of poor quality that cannot be used. Fourth, successful egg retrieval is only a small part of the process. Wait for embryo transfer after 2-3 days. In very few cases, the eggs are not fertilized or the fertilized eggs cannot continue to develop and divide. This may be due to the quality of the eggs or high sperm malformation rate. I myself have had about 10 eggs retrieved and 8 embryos were formed, which should be good, but only 2 embryos were available (i.e. good quality) and the rest had very little chance of forming a fetus, and most of them ended up in miscarriage if they were barely conceived. Some couples wait until the day of embryo transfer and the nurse tells them that there are no embryos of good quality, then the cycle is terminated. Five, 14 days after embryo transfer “prison”, said it is a prison – one means that it is best to lie in bed, because the embryo to wait for the embryo to bed before a little activity (this is safer, so that the embryo does not take root). I basically spent the rest of the 3-5 days after the transfer in bed, except for getting out of bed when I had to pee and poo and eat, and I couldn’t sit for long. Psychological prison – you don’t know if the embryo might fall out because of any negligence or carelessness, or if you push a little when you urinate or defecate, because it’s always a mystery, there’s no way to know the result, and there’s no big movement in your belly, occasionally “pins and needles” The occasional “pins and needles” sensation will make you excited and prove his existence. Some people take a urine test on the 6th day after transplantation, in fact, that is even more self-torture, because a positive urine test is required to wait until the concentration of HCG in the urine is high enough to appear two red lines, there is a window of time, too early to test but make their own blow, some people give up on themselves, shopping, playing, stopping the medication on their own, no longer care, and wait 14 days after a positive urine test regretted too late. 14 days After the “jail”, it is the long-awaited urine test, as if waiting for the sentence, there will be nervousness, there will be excitement, there will be frustration, there will be excitement, there will be trembling, there will be tears …… six, if the urine test is positive, but also to draw blood to test the level of blood HCG and value-added, to understand the development of the fetus. The actual fetus will be in the process of developing. It is inevitable that IVF will result in miscarriage, stillbirth or ectopic pregnancy, so continue to be careful. My nerves were raised again when I found a small amount of blood on my underwear 14 days after the transfer when a positive urine test confirmed a successful pregnancy. A small amount of bleeding in early pregnancy is caused by the embryo taking root and eroding the blood vessels, which is normal and not a miscarriage. Seven, October pregnancy once the birth. Only when the birth of a child is successful is the final success achieved, which should not be neglected. In some cases, the ultrasound after early pregnancy reveals an empty sac, no embryonic bud, no fetal heart, and the embryo stops developing, so the uterus needs to be cleared. I heard of a person who was successfully pregnant with twins by IVF, but after two months, one fetus was naturally reduced and only one was left. In the third month, the fetus died due to unfavorable birth control measures and her own reasons.
