Okay so sunday morning I woke up and had blood on my underwear. I then put on a small small pad that lasted all day since it was so light. Monday was a little heavier but still could use a small small pad. Then tuesday its only there when I wipe and is now completely gone but maybe a couple spots leaking here and there. Me and my boyfriend did have unprotected sex on thursday and wednesday causeI forgot to take my pill those days. Is it my period or implantation bleeding or is it to heavy or from the pill? Oh and my last period was feb 13th. So I shouldn't of got my period for awhile now. Its also a brown color and very liquidy. I picked up a pregnancy test and will be taking it next week.
