Uy, mama, yan kailangan i-mention mo talaga sa OB mo sa next visit, o kahit mag-call ka na ngayon if it's bothering you a lot, para masiguro lang na lahat ok.
Hindi ko masasabi kung normal or not yan based lang sa text, pero alam ko na may mga bagay na nangyayari during pregnancy na kailangan tingnan ng doctor, better safe than sorry, diba? One of my mum friends had similar concerns and nalabas may simple explanation lang, pero important pa rin na na-check. Siguro it's just pregnancy stuff, pero let your OB decide, they'll know best based sa full picture ng pregnancy mo. Sending you good thoughts!
