What Are The Chances Of Healthy Pregnancy In An Overweight Person?

Hi. i got married in april 2014 n got a positive pregnancy test in June but due to some family problems we didn t took it forward and I took pills to terminate d pregnancy on 15 June 2014. Now I m trying to concieve from past four months but no positive result till now. Visited doctor few days back who prescribed Azax 500 for three days and ovagrace sachets for a month. Also asked to get a follicular study done which I couldn t get done in this month. She suggested clomipure from day 3till five days the next tym I get periods. I wish to know if I should get follicular study done in next month? if yes then from which day of the cycle till how many days? Also what are the chances of getting pregnant considering I m overweight but have always had regular periods and Have taken pill in past to terminate pregnancy? Thanks
