Nausea/sick with O

According to glow I was several dpo but I never got a positive OPK during that window, but today I started throwing up for no good reason and wasn’t hungry for my favorite food!

I took an OPK and I had the smiley face, so is it normal to get nauseous when ovulating?

***I’ve been randomly getting nauseous/sick for 1 or 2 days every month with no explanation, this is the first time I had an OPK to test with tho.
