I am 36 years old with one child aged 4 in May. Been trying to conceive for 13 months. Believe I ovulate on day 17/18 (ovulatory pain) with cycles 27/28 days. Husbands sperm is fine (I am embryologist). FSH day 1-4 is between 3 & 6. why can I not conceive????? First child born by forceps, could any damage have been done with this procedure?
