My last period was May 29. I was suppose to start my next one June 23, it didn't come till the 25th. Sat and Sun, it was light and medium. Sun night and Mon, the flow stopped. Nothing came out. Today is Tue and the flow came back but is light and i only see it when i wipe but nothing is on the pad. I had sex the 9th and 10th of June. Those were days that I was ovulating. I used protection, but I'm not sure if im pregnant. Can u help me please.
