cramping.

I'm 3 weeks and 2 days post D&C. I was having my normal ovulation symptoms of EWCM for a few days starting last Friday and then starting yesterday I have been cramping (haven't had sex since Monday bc husband out of town for work). I feel like my period is going to start any minute but nothing. I'm super dry right now so I'm just all sorts of confused. My levels have been down under 20 for a week bc I've been getting negative hpt. Just wish I knew if my period was gunna show up or not. We are already TTC but i really don't know what's going on with my body. Would be amazing if I did get pregnant but I'm really trying to be real with myself and not get my hopes up when AF does show.
