Based from the information provided it seems like you are having "PCOS" i.e. polycystic ovarian syndrome
. Which is basically an imbalance in the hormonal
cycle due to issues in ovary.
Now let me answer the questions.
1) CURE: - treatment you are receiving is the perfect way to deal with "PCOS", OCP
have the hormone what are normally released by ovary and helps maintain periods cycles. But I am sorry to inform that their is no permanent cure for the kind of issues you are facing.
:- Chances of getting pregnant are lower then normal females but its not impossible, their is a separate pill that can be taken for ovulation and may helps to increase the chances for pregnancy
. More over their are many methods to make pregnancy occur in controlled setting in clinics, for more information please contact near by infertility clinics.
More over loosing weight has also shown improvement in chances of getting pregnant.
Hope it helps.
