This is confusing.. I wiped this just a little bit ago. Last time I had a miscarriage in august the whole discharge was red. But this one has like a red/brown line through my yellow discharge I've been having? Currently 7 weeks pregnant. Is this normal? Wiped it a couple times now. But not in the same day. Could I be wiping too hard or what?
