I'm 21 days into my cycle, ovulation was on day 17 I had terrible night, headache, stomach pain, I even heard it burping, I didn't want to go to the bathroom, I felt like I had a fever, I was cold but really hot actually I suffered for 4 hours No strength at all What could it be? Have you experienced this?
