Weird sickness

Tyeshia
Okay so i've been having this weird sickness where i'm very hungry, tired,and nauseous. I've been bloating lately but my period is suppose to be in 3 days so idk. I did have sex a couple days after ovulated and my boyfriend didn't cum in me and used the bathroom a couple of times before we had sex. Has anyone had this sickness i've had it since sunday?
