Talk to Gynecologist on Conceiving

I am Married and 29 years old. I was married 1 and half year back. I have medical history of a miscarriage. I have been taking treatment from very well known doctor , she has prescribed me Clomitab, Gonadil-F, Progynova and Duphastan during certain days of my cycle. I also hhave ultrasound during 13/14 day of my cycle and I have healthy follicles. Its been 10 months now I am taking these tablets, follicles are also healthy and mature but I'm not conceiving yet. I am gaining weight also although I have physical activity and take control diet. My question is should I stop now taking these tablets as its 10th Month now and Im not conceiving though everything is fine. Also is there any harm if I continue taking tablets till I conceive? Need your kind reply please.
