I had a surgical abortion, I have concerns about my future fertility?

I have concerns about my future fertility and hope you can shed some light on my concerns. I am 20 years old and when I was 14 had a surgical abortion when I was just over 11 weeks gone. I have concerns that I may have scar tissue in the uterus due to minimal periods but lately different period pains. After having the abortion I had an implant put in and after that had a second implant which I have recently had removed about 1 month ago. Of course my body is still adjusting but something tells me something isn’t right. My period came exactly 1 week after the removal of my implant and lasted about 5 days which was fairly light. And exactly when my next period was due, it came on time but again very light. Please could you help me understand what may be wrong due to previous operation and having light periods. Thank you.
