I need to know if anyone experiences this or knows what this is or went through it.

I am 36 weeks and i know its normal to have some pelvic pain bevause she is settling in but i am having trouble walking, standing, turning over in bed, and getting out of a vahicle. The pain is almost unbearable. Ive talked to thw dr but thwy just say that its because my muscle are relaxing and what not. But i have a 7 year old and this is not a normal pain. Help me
