Is this normal? Feeling sick when you ovulate?

I just got my positive opk today, so I should be ovulating within the next day or so. All day, I have felt so nauseous, even threw up in my mouth a little bit this morning. I'm feeling dizzy, possibly a slight fever, and just really tired.

If I don't conceive this cycle, my Dr wants us to move from medicated cycles to IUI, so there's no skipping this month lol. This is our "last chance".

I'm just wondering if anyone else gets like this around ovulation. Right now, I can't even remember if this is normal for me or not, and we have been TTC for over 3 years. Could this be ovulation related, or is it likely something completely differentm
