New to this

I'm trying to have baby. Last year I was told that I have cyst on my overies. I talked to my dr and she said that they won't come back because of my birth control and told me that if I wanna get pregnant to stop talking them. We have had unprotected sex for 3 week now and Monday I started bleeding and then stopped yesterday. I have had heartburn every evening for a week. Mild cramps. And been very emotional. And extremely hungry. I took a test last week and it was negative. What r the chances of being pregnant?
