I have no idea what causes this, but I am 20 weeks pregnant and am experiencing the exact same thing. Whenever I sneeze, cough, sit down, get up, roll over or even simply walking...I get a pain in my lower abdomen and now it has traveled down into my vagina. I asked my doctor and she suggested getting a "pregnancy belt" to help support the weight of my stomach. She thinks my belly is putting pressure on nerves and is causing pain.

yep am 34 weeks and av got the excat same thing,mostly when im walking and the midwife told me it the baby putting pressure on my nerves.

i have the same, im 36 weeks. but mine is because the babies bum is sitting on my cervix (his breech) and because his bum first his dropped further down then a head first baby because is bum is more narrow then his head. its very painfull

I am 34 weeks. My gynae says it is normal as some ladies face this due to over working like bending, walking, stretching, exerting ur muscles. Its a liagarment/muscle pain.

Solution: Bed Rest and reduce stressing urself. u can get medicines from ur doctor.

I'm 32 weeks pregnant and experiencing pain on my right side it also feels like a pulled muscle .
