Terrified bleeding 6 weeks

Alisa
Last night after a trip to the store I went to pee and there was a tiny blood clot and light pink on the tp.  I of course lost it because I've had two mc before.  The whole night I didn't sleep kept checking.  It eventually turned brown which wasn't on the tp I checked myself tmi and then this morning same barely there.  Still no cramps and took a test bfp still.  I'm 6w1d.  Has anyone experienced this before?
