Weird😕

So.. I had an iui Thursday (may 12) I am currently 4 days past iui I had a hcg trigger Tuesday (may 10) . I know it's too early to test but I am having period like cramps but my af isn't due til the 28th. I don't get cramps a week early... Ever.  I just had a chocolate chip cook from my fav cookie store and as I took a bite of the last one I automatically threw it up. It tasted horrible, and I loveeeee their cookies! I've been having hot flashes today. Had a Charlie horse Friday and hurt like crazyyyyyyy haven't had one of those in years. I been having a gagging feeling all day today but nothing comes up except that chocolate chip cookie I just ate. No bleeding yet and been very gassy. Also this is my first iui so this is all new to me . I go back to my doc Thursday to get my blood drawn for progesterone levels. Until then I'm keeping tabs on my symptoms.Has anyone been through this and has had a BFP?
