IUI and sleep?

GlendaG • Started TTCing for #1 in Nov 2013 Married June 2014 stopped TTCing Dec 2015 now just living
Hey had my <a href="https://glowing.com/glow-fertility-program">IUI</a> Saturday was as bloated as a house Saturday night but most of that went away. Yesterday I got home around 11am from chores and slept for 5 hours, today I got home from dropping my stepson off at school and slept for 4 more hours.
 Both days I've had to stop and get  something with surgar just so I did not fall asleep on the road. I barely was able to keep my eyes open on the road. I was exhausted all night last night until bedtime and had to fight to stay awake.
Today I'm still tired after my nap is this normal after <a href="https://glowing.com/glow-fertility-program">IUI</a>? I want to think it's a possitive sign my body is trying to make a baby. My pessimism tells me I'm being silly. Please let me know if you experienced this after <a href="https://glowing.com/glow-fertility-program">IUI</a> and if so did it end in pregnancy.
