Yesterday and the day before, I spent the whole day nauseous. Af was due yesterday. First time to restroom this morning I has a fair amount of discharge, kinda orangey in color. Second restroom trip there was nothing. Just had "sexy time" with hubby and while cleaning up after, there was a less-than-pea-size clump of mucus that had a brownish tint to it, but very light color. Implantation or af??
