Aww mama, right side pain during pregnancy can be tricky kaya I'd really suggest checking with your OB na lang talaga, especially since you're at 17 weeks, it could be round ligament pain (super common sa second trimester!) or something else na kailangan i-rule out ng doctor. In the meantime, try resting with your feet up, stay hydrated, at avoid sudden movements muna, pero don't wait too long if it gets worse or you feel dizzy ha!
