Thanks for posting your query. From what you have said, I infer you had ovulation induction for 6 cycles with clomid and ovarian drilling apart from injections for egg release. The fact that you had a follicle of 22 mm is re assuring . But you could have a condition called LUFS- lutenized unruptured follicle syndrome and this is more common with clomid. You can still try ovulation induction with or without IUI , but instead of clomid or with clomid in lesser dose, you can use hormonal injections to induce ovulation. I assume your partner s semen parameters are optimal and your tubes have been checked. Taking metformin helps . Please continue folic acid during this process. Wish you all the best, take care!
