pain in pelvis/crotch

I hit 30 weeks today, and started feeling pain/pressure in my pelvis and crotch around 27 weeks. Well today I picked up something a little heavier than I should have and felt an intense pain in my crotch...to the point where I can hardly walk normally. Baby is ok, as he has been moving around in the last 6 hours since I picked up the item. Can anyone relate? I feel like someone kicked me in the crotch. 😣
