Is anyone else not able to sit in comfy seats?

Began to notice at 5 weeks of this pregnancy that I cant sit in comfy booths when we go out to eat or in a comfy couch period. I started to have lower back pain within 10 minutes of being seated at ihop. Since I had a miscarriage with our last baby, I was kind of scared but noticed the pain went away when I switched positions. Today, Im 11 weeks pregnant and I guess that back pain is probably bound to get worse the further along the pregnancy. Next week is my 28th birthday and also when we plan on announcing the pregnancy to our soon-to-be 8 year old big sister. Right now I'm sure she enjoys having to take mini girls trips to get my cravings filled too! Right now the bump just looks like im sticking my belly out most of the time! All will be worth it for the blessing we have been longing for!
