Hay, I'm sorry you're going through this, mama, it's such a confusing and emotional time. After a miscarriage, it's actually normal for the PT to stay positive for a few weeks kasi ang hCG hormone takes time to fully leave your system, pero 2 weeks and still clearly positive, it's better to check with your doctor na to make sure everything is okay and to confirm kung talagang na-pass na lahat or kung may complications.
