So I started bleeding on the 11th late at night right after having sex with my husband. I figured I was getting my period. I was bleeding most of the day on the 12th and then on the 13th I would bleed on and off. Yesterday (the 14th) I didn't bleed all day till last night just had a little spotting when I would wipe. Today no blood again. Does this sounds like a period? Or what could it be? My period wasn't supposed to start till yesterday.
