Uy mama, headaches at body pain in the third trimester ay common talaga, pero since you're experiencing these together, please check with your OB soon or go to your nearest clinic to be safe, hindi dapat palampasin yan ngayon na malapit na due date mo!
A few of my mum friends had similar aches towards the end, pero importante talaga na i-monitor ng doctor, lalo na yan kung ito ay baguhan para sa iyo. Take care of yourself, and don't hesitate to reach out to your doctor if it gets worse, okay?
