My husband and I got all tests done which were normal, and doctor asked for follicular study and then after day 11 she gave HCG injection for ovulation and we were asked to have coitus after 36 hours then report for a scan...we went and found that follicle has not ruptured and then she gave another injection inorder to rupture and the next day we went for scan.she said it was ruptured and gave progesterone tablets and asked us to continue having coitus. Did not conceive as I got periods on day 28 . What would be the problem and what I need to do . Please kindly explain.
