Feels like I'm ovulating again?!

Laura • Straight edge, vegetarian, feminist, lover of animals.
I am estimated to get AF this Thursday, I ovulated on the 19 may. I think I have been having some pregnancy symptoms, extreme fatigue, cramps since a week before AF, and a little nausea. However today it feels like I'm ovulating again! I don't have a lot of CM and my cervix is hard and low, is it possible that I'm just getting my period even though it feels nothing like it?
​Any advice or stories ?!
