erica
I'm on cd 41 I'm 9 days late. My cp has been pretty high I can't really tell if it's soft or hard an it feels closed to me. I haven't spotted any but this morning I was checking my cp An when I wiped my finger off it had a brown color on the tissue it was really light but smelled like iron kinda. My nipples has been wet when I take my bra off An leaves clear dried stuff in my bra. I have a 5 year old sonit has been a really long time since I have any symptoms of being pregnant. I have also took test the beginning of this week an it was neg. could I still be pregnant or is this my body playing tricks
