It seems to me that you have PCOS
i.e. Poly Cystic Ovarian Syndrome. This is not a serious problem in the sense that you are not really ill but you may be having any of these 5 features of PCOS, in alone or combination - obesity; no release of egg; delayed periods; infertility
and male features like excessive hair growth
on beard and moustache area, oily skin, acne
The treatment prescribed by your doctor will help you in decreasing weight and in normalizing the insulin resistance
. Give it 2-3 months more and you may conceive by yourself. Remember to have intercourse in the fertile period during this time. The fertile period is from 8th day from start of period for next ten days. Have intercourse every alternate day. Daily intercourse may decrease the quality of sperms in the semen.
To help you conceive you can also take egg releasing medicines for 5 days. Discuss this aspect with your doctor who will then prescribe it.
The chances of your conceiving are high so don't worry. Since the egg is released only once in a month, every time its not released or it has not been able to fertilize, you have to wait for next cycle. This may lead to great upset but if you understand the reason behind it, it makes it easier to wait for conception to occur month after month.
Hope this answers your query.
