Iui symptoms

I did <a href="https://glowing.com/glow-fertility-program">iui</a> on the 18th of June and 2 dats later until now I’m waking up nauseous in the morning .. no other symptoms I know that it can also be rising progesterone level but anyone else with me? It goes away curbing the after noon. It’s weird because I feel it in my sleep too. I’ve never felt this and this is my 3rd <a href="https://glowing.com/glow-fertility-program">iui</a>..
