Husband and I have been trying to conceive for 3 years, had tests done and have a 1.5 progesterone level, so we will be seeing a fertility doctor soon. My question is I am 8 days late, took home pregnancy test was negative. But today, I had blood in stool, and still no period. I have sore breasts and slight cramping like I always do before my period, but my period is always on time, what could be causing this. I was told I would only be able to become pregnant, if I started clomid or other options. We have no children.
