Uy mama, upper left stomach pain in pregnancy can be a few things, kaya please go see your OB soon or go to the hospital if it's getting worse or you're worried, better safe than sorry, 'no? A few of my mum friends had similar pains around that stage, and most of the time it was just the baby growing or ligaments stretching, pero kailangan talaga i-check ng doctor para sure. Wag mo palampasin ang check-up mo, ha, at 32 weeks yan important stage na. Sending love, you've got this!
