Hi this is first time, i am in any group. I am  trying to get pregnant for 7 years and  all the doctors told us, it is male fertility. So three years ago we did two round of failed <a href="https://glowing.com/glow-fertility-program">iui</a>. Then in 09/16 we did our first <a href="https://glowing.com/glow-fertility-program">IVF</a>. And i had one fertilized egg out of 4 and did transfer on day 3 but <a href="https://glowing.com/glow-fertility-program">IVF</a> failed because of implementation. We then started 2nd <a href="https://glowing.com/glow-fertility-program">IVF</a> on April 2017 but only grow one follicles and cycle got cancel, then i started 3rd cycle on may 2017 with lupron but cancel again because of small follicles. I am going to start another cycle in june 21. I am very worried, about what is going on with my body and i all my test in these 7 years were normall and never had any infertility problem but i do not know why my body is not responding to the medicine. So worried . I do not know, i should start another cycle or stop it to give my body rest. I am also taking prenatal, Coq10, DHEA and vitamin D for last several months to give my body extra boost.
I am 33 years old husband is 37 year. Any advise will be helpful.
