Been feeling really crap today.

Rosie
So this evening I've been feeling really crap! 
My stomach feels like it has a heart beat! 
It's a horrible feeling & it's making me feel really sick! 
I've not eaten much because of it. 
I'm also so hot & been really tired all day,  
Do you think I could be pregnant or just ovulating?! 🙈
My period isn't for another 13 days so I think it's still abit to early for me to be pregnant?
