Ttc/period?

Gina

I don't know what to think...So this is my 3rd day with a missed period. I took a pregnancy test (just for the hell of it because it was a dollar lol) and negative...A few hours go by and (sorry if TMI) but there was I guess you could say spotting although it wasn't red it was more brown. I lost my daughter in December at just about 35 weeks. I have had 2 or 3 regular periods....What do you guys got for me?
