Nak, that needs a doctor's check-up ASAP, lalo na may tigas ng tyan ka pa, hindi ito dapat i-wait. Please go to your OB or emergency room today para ma-check properly, okay? Bleeding during pregnancy can mean different things, and you need professional eyes on this para sure ang baby niyo is doing fine. Huwag mag-alala, maraming preggy moms ako kilala na nag-bleed din but nabigyan ng proper care, so go na po!
