Hi, I recently found out I hv long irregular periods, the Dr gave me folic acid pills with duphaston to take for 10 days in three months interval. My periods started from 9th Aug to 13 Aug before I started the 10 days treatment. I started 10 days medication on the11th and now on the 21st I started menstruating again. When is the right time to fall pregnant? Im confused??! On Which date will I ovulate?
