Confused... 8dpiui hot flashes, headache, nausea..

Alaina

So this cycle was my first clomid/estradiol/hcg trigger <a href="https://glowing.com/glow-fertility-program">IUI</a> cycle. I'm 9dpt 8dpiui and having hot flashes, headaches, and nausea all of a sudden. I woke up feeling fine then a couple hours later, instantly felt sick for like 10 minutes and now I'm totally fine.. Do clomid side effects last the entire cycle? I'm pretty sure its still to early for anything pregnancy related. So I'm guessing its from the clomid I took cd5-9.. Any input?
