Okay, so I had my period on the 1st or 2nd and it only lasted 2 days. I'm pretty used to it because I have mirena in and can go months w/o af and then get spotting, heavy, or light periods. About 6 days ago, I started having this brown discharge and it lasted for 3 1/2 days, no pain with it. Last night I decided to test and got what seems to be a VERY faint line. My husband says he doesn't see anything and I'm wondering if it's either a control line or I'm just imagining seeing a line, or is it really a BFP.
