Uy, I can feel how worried you are, and that's completely understandable. But honestly, para sa ganitong concern, kailangan mo talaga ng proper medical guidance, please see your OB soon or go to the ER if you're experiencing heavy bleeding or severe pain. They can do the right ultrasounds and tests to give you a clear picture, hindi lang basta-basta.
A few of my mum friends have been through pregnancy scares like this, and the waiting period is really stressful, but their doctors were the ones who helped them know what's really happening, kaya please don't rely on stories alone. Every situation is different, at kailangan ng professional assessment para sa peace of mind mo. Thinking of you, mommy.
