I started having my periods when I was 12. It was regular at first, then when I was 15 I was diagnosed with Polycystic Ovary Syndrome (my mom has it too). I am now 22, and have my periods usually every 6 months. My last one was in September, and now I've had one for the past 2 weeks. It's heavy and annoying. I also have back pain and I fall asleep even when I'm not tired. I also noticed my belly hurting a little. Could this be an underlying problem in which I should contact my GYN? Or could I finally be pregnant, considering my fiancé and I have been trying for quite some time now?
