Aw, mama, headaches during pregnancy ay common talaga, pero kung sobrang sakit at palaging nangyayari, kailangan mo talaga i-check with your doctor or OB para sure. Hindi ko dapat mag-assume kung normal lang ba o may kailangan i-address, mas safe na marinig ang professional. A few of my mum friends had the same concern, at nag-worry din sila, pero after check-up nila okay naman. Kaya please don't delay, go see your OB soon, especially if worsening na or may other symptoms kasama. Sending you healing thoughts, mama!
