Anyone TTC and fresh off an IUD?

I had my IUD removed about two months ago now. Luckily my period came back within 4–5 weeks over removal. My first ovulation was pretty normal, all the textbook signs, positive tests, etc. My next period is set for five days from now. I have had a really hard time adjusting to the hormone spikes. Has anyone else had that? I go from happy to cranky to weepy all in one day.

On top of this, today after breakfast, my husband and I ran in to grab a couple things at the grocery store… I had to sprint to the bathroom to puke. It hit me so suddenly. Since, even if I were pregnant, I don’t think this would be morning sickness yet. I am assuming it’s all the hormones. Has anyone else had this much whiplash coming off of an IUD?
