has this happened to anyone ...

I'm on the 4th fertile day of my cycle ... and the last three days I've had slight nausea ... today it's beyond belief , I feel like I'm going to vomit , every smell is bothering me . I was showering and after my shower I got the watery sensation like I needed to vomit . Now I'm sitting in work , I've been eating so it's not lack of food , but I feel like I'm going to throw up it Comes and goes . Does anyone else get nauseous
