Uy, I know how scary and confusing that feels, two weeks delay, negative PT, tapos may bleeding. But honestly, I can't tell you what's happening based on that alone, at kailangan mo talaga makita ng doctor para ma-check properly. Could be maraming reasons, and you deserve to know for sure, hindi lang guessing game. Please go to your OB or nearest clinic/hospital so they can do an ultrasound at blood test, that's the only way to get real answers, mama. Wishing you clarity and peace of mind soon.
