I've had sex (unprotected) on my fertile days which was the 11-16. Mu last period was 4-10..I've been getting wet discharge it's clear and doesn't have an odor. It gets to the point where I have too keep changing my panties. I've also been extremely nauseous and went to a cook out yesterday and the smell of the food made me want to throw up. What is happening? Is it too early to feel nauseous?
