Second miscarriage?

Ashley
I had a miscarriage back in December. I was 7 weeks along. I'm now pregnant again and wondering if I'm going to have a second. Right before I got my BFP, (probably 13 dpo) I had some brown tinted discharge, I thought my period was trying to start but then it just never came. I'm cramping on & off, and yesterday all day I had diarrhea spells (sorry...TMI). Can anyone give me any input? Don't be afraid to be honest if this has happened to you and ended in miscarriage, I would rather know.
