The clinical pregnancy rate of IVF fresh cycle is only about 50% after all. Before starting IVF, you must have a red heart and be prepared with two hands, if you get pregnant, of course, it is good, if you are not pregnant, what should you do? First of all, stop all medications (such as progesterone, Glivec, etc.) and wait for your period to come. After your period comes, if you are a patient with polycystic ovary syndrome, you should use Mafron or Daine-35 again to adjust your period, and after your third period is clean, come to the hospital and register for specialist clinic to see if you need to do hysteroscopy and other tests. Secondly, if you have frozen embryos, come to the hospital around the 5th day of your fourth menstrual period and your doctor will decide whether to use artificial cycle or natural cycle depending on your follicular growth and endometrial status. Artificial cycle means using supplemental Glaxo, while natural cycle is to monitor the follicles and schedule the transfer after ovulation. The clinical pregnancy rate of our frozen thawing cycle is 50-55%. The cost is $2000. Again, if there are no frozen embryos, your doctor will recreate an appropriate protocol for you based on your last protocol and the embryo situation, but the cost is similar to the first time. Some patients have very poor ovarian function due to age and other factors, and only 1-2 eggs can be retrieved, which greatly reduces the pregnancy rate. The doctor will advise them to give up the treatment and they can use methods such as egg donation or cuddling, at which point you should calmly consider whether to proceed or not.
