Ay sis, nosebleeds during pregnancy are super common talaga, especially sa second trimester kaya hindi ka nag-iisa! Since your OB already pinpoint na ang aspirin ang culprit, definitely follow that advice kasi siya ang nakakakita ng buong picture ng case mo, maybe she'll adjust the dosage or timing, or may alternative na safer for you. The good news is from your first pregnancy experience, the bleeds weren't heavy and you felt fine, so alam mo na your body handled it well before, pero still best to check in with your doctor ulit about this nosebleed if it feels different or heavier than last time, para mapakali ka talaga!
