I had sex with my boyfriend the last days of my period , he. Cummed inside me but something fell out. Later we stopped for couple days and I noticed that my period stopped. The few days we didn't have sex I had no spotting. We had unprotected sex a few days later , he did not cum inside of me but the next day I was bleeding light, and brownish. Then the next day I started having heavy blood when I pee. Did my period come back ? Or is this something I should be alarmed aabout. It looks like it could be my period again but the new month is already starting so will this effect this months menstral cycle.
