How Long One Should Take Ovacure

I have been taking Marvelon 21 and I have PCOS. My sister recently advised me to drink Ovacure. Just want to confirm if that will interfere with the contraception effect of the pill? Cause I just want to get cured from PCOS but still avoiding pregnancy at the same time. Thanks for any responses? :)

I'm using Ovacure and Neomet as per my dr. advice. I've been trying to have baby from the last two years. Both of us (my husband and I) did a check up and there is no problem, however I am still not getting pregnant. Finally my dr suggested I take these two medicines, and also one injection sth like Monopore. I don't know why she adviced me these? Will these help me get pregnant? Thank you.
