Patient: Description of condition (onset, main symptoms, hospital visited, etc.): Dr. Tian, I am your patient, after the egg retrieval on July 5 (embryos have been frozen), my period came on July 15 (7 days early), before doing IVF my cycle was very accurate usually at 29-30 days, but I don’t feel like I am going to have my period until today. 1. 2.If I get my period on the day of menstruation, can I come for transplant this cycle? Above: Hello! After super ovulation, especially the long or short protocol, the pituitary gland function has been affected by the medication and menstrual disorders are inevitable afterwards. In this case, there is no need for medication to “regulate” the menstrual cycle. What you need is time, and only time is the best medicine to restore your current endocrine system. When you can start the subsequent cycle of freeze-thaw embryo transfer after ovulation promotion depends on the degree of endocrine (menstrual cycle) recovery mentioned above. In general, I advocate starting freeze thaw embryo transfer preparation on the third menstrual cycle after ovulation.
