Miscarriage

About 2 weeks ago i started what I thought was my period after being 11  days late. When I thought I had started i was VERY VERY light, and only lasted 2 days. And keep in mind I have NEVER been that late to start my period. Then yesterday, exactly 2 weeks after what I thought was my period, i started bleeding again. This time im bleeding normally, and this is the usual time for me to start. I never took a pregnancy text, but im thinking I had a miscarriage. For a little over a year now I have had bad cyst on my ovaries... And for the past 2 years I have had completely unprotected sex, and never gotten pregnant with him coming inside of me... Im really questioning if i can get pregnant, and if i was im wondering if I miscarried.
