Mama, dahil na-experience mo na ito ng more than a week at 24 weeks ka na, please don't wait, go see your OB this week talaga, okay? Lower abdominal pain during pregnancy can mean different things, at kailangan talaga ng doctor to check properly.
A few of us moms had similar concerns at iba-iba ang reason (ligament pain, round ligament stretch, sometimes other things), kaya hindi safe mag-assume lang. The fact na umuulit-ulit at nag-shift yung pain location makes it extra important na ma-assess ng doctor immediately.
Please don't worry too much yet, most cases ay okay lang naman, but you really need that checkup na to be sure. Praying for you, mama!
