Ladies PLEASE HELP

Okay so since i woke up I’ve had intense lower back pain on my left side, throughout the day it got worse i took 2 Tylenol’s and nothing I can’t even sit to pee or bend, earlier I almost collapsed because my left leg can’t take the pain.i also have a hard time walking. I literally cry of pain and nothing no pillow or laying down a certain way helps it’s really bad I’m currently 16 weeks. I’m embarrassed to even ask because then people might say “giving birth isn’t any better so good luck” so please just genuinely help me. I plan to call my doctor first thing in the morning!
