Alam ko yan, first time kaya everything feels unfamiliar and scary! Some discomfort down there during pregnancy is pretty common, the pressure, hormones, and stretching ng ligaments talaga nag-cause ng aches, pero since nag-aalala ka, best talaga to check with your OB para ma-rule out kung may infection or other concerns na kailangan i-address. A few of my mum friends had similar worries around mid-pregnancy, at the doctor assured them it was normal, pero sabi nila peace of mind talaga ang nakuha nila after that check-up, so don't hesitate to call your clinic, ha!
