Am 20week pregnant I started feeling the same. I had same type of pain in back too but now i feel like it moved to front. It's bcz of our uterus is growing big & bcz of that it's putting pressure on pelvic bones. So don't worry. hot water bath helps me a little
I didn't have the pain while pregnant with my first either but it started when I was about half way with my second and I got it again immediately when I got pregnant with my third. I just deal with it. Nothing really helps so I just complain while at home and try to tough it out while out in public. Sleeping with a pillow between your legs sometimes helps a bit but not too much so I just stopped that.
I've had 2 precious pregnancies...and NVR had this pain...
And its horrible...how did you deal with the pain?..
Unfortunately it's pretty normal and just gets worse the farther you get. If you're really concerned you can call your doctor if you want though. They'll probably give you some ways to reduce the pain.
