I'm on my fertile week and I wiped and this showed up on the toilet paper, tomarrow is the last day of my fertile week, I've never wiped before on my fertile week and seen this.. I had some brown stuff last night on the toilet paper. So does anyone have a idea of what this is?? We have been trying a lot to conceive and this month we have been having sex a lot. We been using Preseed and even had sex on my period. I've been having cramps also! Thanka
