I have the same experience but im 6-7weeks
Do you have the pain all the time ? Of on and off . You know I even scared to were pants I least wear dresses
I felt the same and was scared. I also told my doctor and didn't even check me, all she said it was "normal" so I was still kinda worried. but after a couple weeks it went away.
It could be the baby movements I had same problem I'm now 33 weeks and in way more pain in the lower part of my back pants are extremely uncomfortable for me i wear shorts and dresses to
