I was on birth control (the shot) in August and didnt get it again (was to by Nov. 26th) because my fiancee and I are wanting to have a baby. I haven't had a cycle yet but I spotted once last week. I went to the doctor and she told me that I can become pregnant without having a cycle. She also advised me to start taking prenatal pills and I went and bought some at Walgreens and began taking them 2 weeks ago. Will that help or what, how will I know when Im ovulating though I dont have a cycle? Is there anything for me to take to get a cycle again suck as the pill or what?
