Mama, please see your OB right away, subchronic hemorrhage during pregnancy needs proper medical check-up talaga, hindi dapat i-postpone. I know it's scary, lalo na you're only 8 weeks, but doctors need to assess what's happening with baby and you. I can't tell you what caused it kasi yan talaga ang work ng doctor to figure out, there are different reasons and they need to see you in person. Puwede nang maging okay, pero kailangan ng professional na tingnan. Praying for you and baby! Keep us posted once you've seen your OB, okay?
