Sitting Comfortably

Chloe
I'm only 8.5 weeks pregnant so I'm surprised this is becoming an issue so soon since I'm not showing at all. 
I enjoy tucking my knees into my chest to watch tv or read a book in bed. Lately though it has been feeling uncomfortable to sit like this because my lower abdomen is so tight. Has anyone else had this issue? It's irritating since I'm a side sleeper I thought sleeping would be fine for me but trying to sleep with my knees tucked in is way too uncomfortable!
 Any other fetal position sleepers out there starting to have this problem?
