Pressure

Samantha • I am me.
Sooooo I've talked about this before but the pressure in my pelvis is getting worse to the point where I'm really really sore and it's difficult to get up out of bed or from sitting and it's difficult and painful for me to walk. My doctor said its normal to feel pressure and back pain but to what extent is alarming? It's a very sharp pain and I'm to the point of not being able to handle it anymore all I wana do is just stay in bed for the rest of my pregnancy. 
I'm 36 weeks 3 days pregnant.
