Oo, super normal yan sis! 28 weeks at first time mo pa lang, so ang katawan mo talaga ay struggling na sa weight at position, a lot of my mum friends said the same thing during their third trimester, nakakagulat kung gaano kadaling masakit ang buo ng katawan. Try sleeping on your left side with a pregnancy pillow (sobrang game-changer yan!) or kahit regular pillow between your knees para sa support, and don't worry if kailangan mo mag-adjust every hour, that's just how it is when you're pregnant na ganyan kalaki na. If the pain is really intense or nag-cause ng major discomfort, check with your OB lang to make sure everything's okay, pero honestly most of us just embrace the "aahing and oohing" through the night na!
