Uy, nosebleeds during pregnancy are super common, sis, maraming preggy friends ko na-experience din yan, kaya hindi ka nag-iisa! It's usually just because your blood vessels are more sensitive and your blood volume increases when you're pregnant, so it can happen na lang talaga, lalo na pag dry ang panahon or if you blow your nose hard.
That said, habang normal lang siya mostly, good idea pang rin na i-mention mo sa OB mo sa next checkup para ma-assure ka talaga, minsan kaya naman ma-manage lang with simple tricks like using a humidifier or being gentle when you blow your nose. Excited na ba sa baby mo?
