I am 6 weeks 2 days pregnant with my rainbow baby. I had a miscarriage previously on Christmas Day. Everything has been fine as far as having symptoms. Nausea started last Saturday so it was a sign that everything is okay (my first appointment is March 22). Today, a few times I have wiped and it was a really light brown color. I put a panty liner on and nothing is there, only when I wipe. Should I be worried?
