I have pain down low too, but I'm further along . I'm 33 weeks and 3 days . It hurts when I go to stand up or roll over in bed or put pants on or bend over . I have to do it all very slow . It feels like the bones all down there are bruised . 100% normal . It's definitely just your pelvis and pubic bones stretching because of the relaxin horomones being released in your body . As long as it isn't inside that youre feeling the pain then youre fine .
As long as you don't feel like you can feel the baby pushing down you're fine. Try some pevic twists & a heating pad it could just be round ligament pain. Totally normal.
