Fatigue after IUI?

I’m 6 days post trigger and 5 days post IUI. I’ve been taking progesterone suppositories for 5 days now and aside from the extra cm, I’m REALLY exhausted 😩. I’ve had an extended weekend (Canadian Thanksgiving) and I’ve been napping daily. They’re those really exhaustive hard ones. Had anyone had this as a side effect of the progesterone? I’ve been reading online (I know not the best resource) and it says it can cause excessive exhaustion and mimic pregnancy symptoms. I just need to shake it off because I won’t be able to nap the rest of the week. 🤦🏼‍♀️
