I have been off birth control for about 3 months, and have had irregular periods since then. My period seemed to start to get normal, but I just started spotting 14 days after the beginning of my period. I don't know if I'm just having my period again or what. I shouldn't be pregnant, unless I ovualted when I thought I wasn't supposed to. The spotting isn't very heavy at all, but I do have to wear a tampon. It's kind of pinkish and also brownish. Is this normal?
