Hi, I had an etopic in march and lost the baby and my right ovary, after my recovery doc discovered a bleeding cyst. She told me that we first going to try "Ovral" a week later my cyst was gone. I had to take it for 3 months, I moved over to yasmin and must not have my period (had to skip it) now it's the fourth month and I'm supposed to have my period. I am on my 3rd "sugar pil" and still no sign of my period... what could be the cause? Should I worry?
