It started around the 20th and I’ve thought it was my period. For about 7 days it was consistent and I was cramping. After the 7 days it got lighter for about 3 and they stopped for a day. It came back brown and then stopped again. Now it’s bright red. This has been going on for two weeks. I’ve been on the same birth control for 2 years and this has never happened. It’s it PCOS? should i be concerned?
