My husband and I have been trying to conceive for a few months now. Normally my period is like clockwork. I am expected to get my period on the 17th this month. Yesterday (Aug. 13th) after peeing, I noticed brown discharge when I wiped. I thought I was just starting my period early, which would be extremely unusual for me, but only had the discharge when I wiped. Nothing in my panties, and no flow ever came. Is this normal?
