I agree - if you're worried, give your midwife a call but i wouldnt be worried. im 28 weeks and my baby chooses some v awkward positions! Her feet go under my bladder and she kicks up - that kills!!!! She gives me some good wallops and they can be painful!
I had that around that time and it was cos my one was always moving in the same area for example always kicking me in roughly the same spot so that got very sore as well as then sticking bum out far in same place - became sore etc etc
yes, there's a special spot that my baby kicks, usually really hard, and it's impressively painful given the size of the unborn!! I usually yell and then say "gently sweetie, don't hurt mummy" thinking that of course that's going to help
My boy definitely gave me some pain at times, including a few scrapy scratchy feelings against the inside of my tummy...he was born on Monday with MASSIVE long nails so yes, I'd say movements can hurt!
