struggling

every night I lay in bed I'm thinking ok this is comfortable I can get some good sleep but when I wake up or want to get up to use the bathroom i have a hard time getting myself up I even struggle rolling from side to side! all I could think the reason why is because babygirl is about 6 IBS! and I guess her weight is what's making me have a hard time getting up?? oh and she also causes me some constipation pain :(. I have 4 weeks left 29 days until she is here I just know it's going to get worse until then :(. but when I first see her I'm just going to forget all she put me through lol
