Round ligament pain. Super common! Google it--lots of info out there :)
maybe your ligaments. THey do become more relaxed in pregnancy. I know sometimes if I get out of the car too quickly or change a position I can feel it in my hip area, but then it goes away.
Everytime i sneeze or cough. Its your ligaments. The effort pulls on your ligaments and it hurts. Should go away after a minute or two.
