8dpo symptoms anyone?

Hi

First off I am not symptom spotting and I dont think I am pregnant. I had a MC in Feb and boy have I run the gambit of symtoms. To twinges and pulling exactly like I had when I was pregnant. I swore to DH I was pregnant... nope I wasn't. This month which I thought was going to be my "normal" cycle. So much for that. For the past 3 days I have had very mild nausea on and off. Today was totally different I had the increased saliva and the icky feeling that I needed to vomit. That calmed down this afternoon thankfully but still nauseous. It was replaced by dizziness and right side cramping. I have been eating and drinking. Is this just Progesterone going wonky? My cycles have been 36 days and 25 days thus far. I have been ovulating early as well this month was Cd 13. Any advice? Has anyone had this after early miscarriage? Thanks everyone!
