Ay, mama, any pain during pregnancy needs to be checked right away, please see your OB or go to the nearest clinic/hospital, lalo na kung tumatagal or lumalaki ang sakit. Better safe than sorry, lalo na kang 9 weeks pa lang. Puwedeng maraming reasons, some normal, some kailangan attention, kaya talaga kailangan ng doctor para ma-check properly. Sending you love, hope it's nothing serious!
