am i or aren’t i ?

around the time of my first couple periods around 14 i noticed that my time of the month was more like time of the months so for a few months back to back were a non-stop bleeding obviously this concerned me and put me in mad mood swings and create a lot of pain so I went to the doctor. The doctor put me on birth control for regulation and I was totally fine. It did help with things but then she began to explain that my chances of having children with bar none now Im now in my early 20s in a loving relationship and I don’t know if this is actually a possibility or not b/c ngl havent been practicing in the safe sex 😅 but i also don’t wanna hold risk of having my one && only chance at having my “miracle baby” and Having an abortion because I’m not ready
