Hey Ladies! 
So I'm currently 6 weeks pregnant. I've had two miscarriages years ago and was finally blessed to have my son in 2015. I've been spotting all week but only enough to notice when I wipe. Today, things have changed because now I'm staining my underwear (sorry for the tmi). I was in the ER on Friday and they said everything looked fine. Since I'm actually staining it's freaking me out. Has anyone experience this before? I have already scheduled my apt with my ob which is next Monday.
