Alam ko yan, Mamsh, minsan talaga may sharp pains sa pelvic area especially when baby's moving or kapag nag-shift ka ng position, kaya normal lang yan most of the time! Pero since you're almost in your third trimester na, better check with your OB just to be sure it's nothing like ligament stretching or something else, lalo na kung may pattern or if it gets worse, yun lang para peace of mind mo, kasi one of my mum friends had similar pains and it was just normal pregnancy stuff, pero important na i-monitor lang talaga.
