احاول ان احمل تقريبا ولكن مح تي بائت بالفشل اجريت فحوصات عديدة وكل شيء

It is difficult to comment on all the aspects related to fertility problems in such a short reply. I am not sure if you completed all your investigations including a test to confirm that the tubes are open and a test for your husband's semen. The ovulation usually takes place 14 days BEFORE your NEXT period, therefore is your period is reasonably regular and you can tell when it will start next. Count 14 days and that should be a reasonable estimate of the day of ovulation. Remember that the egg lives up to 24 hours and the sperm 3-5 days, therefore I advise you tom have more intercourse around the time of ovulation but also although the month apart from the bleeding days. Please complete your investigations if not all done and see your doctor. Regards
