IUI, progesterone, & symptoms - too soon?

Had my first round of <a href="https://glowing.com/glow-fertility-program">IUI</a> done on 4/28 & 4/29 (did 2 transfers writhing 24hrs). Had blood work on 5/2...progesterone was 4.4..now on oral supplements (200mg) three times a day. 

Yesterday & today - I'm very dizzy, almost feel tipsy and nauseated. I know the side effects of progesterone are dizziness, nausea, & even vomiting....but they could also be pregnancy symptoms....

Side effects from the meds? Pregnancy symptoms? Too soon? 

Any input, experiences, advice?? 

Baby dust to all!!!
