Iui treatment please advise?

I would be very careful. There was a reason why this cycle was cancelled. 9 mature follicles is way too many and puts you at a HUGE risk for a high multiple pregnancy - even if you don't go through with the IUI and just BD on your own. Ask your doctor for his/her advice. Is it ok for you to BD this cycle and still try to conceive or should you skip this cycle and try again next month?
