Hi! How are you? I need to talk to a gynecologist, I have a big problem. I have period changes. This problem has started 10 years ago, the doctors told me that I had cysts. Last year the problem started again. My period came every 8 days. I took primolut for 14 days according to the doctor instructions. Everything was ok after that, this year the problem started again, I am taking Yazz, according to the doctor instructions again. I m so afraid, what do I have?
