Anymore get sick during ovulation?

I've noticed that I get super sick during ovulation. Soon as my fertile window starts a day later I'm super nauseous and no appetite at all! I have one child already and I feel like I did when I was pregnant with the whole morning sickness phase that lasted my house pregnancy all day every day. Just wondering if maybe it's the hormones that's making me sick. These ovulation test are from today and yesterday! But it says my fertile window ended yesterday. I'm just so scared and confused on why I get so sick atleast once every month! I doubt this is my GERD or IBS. Even tho it could be. Someone help! I'm miserable.
