Anak, this is so serious at kailangan mo talaga ng doctor right now, please don't wait, go to your OB or emergency room immediately kaya sila ma-examine at ma-ultrasound ng maayos. Interstitial pregnancy ay special case at kailangan ng expert care talaga, hindi lang basta advice online. Nakakaawa ka talaga, nandito kami para sa'yo. One of my mum friends went through something similar at what helped her was seeing a trusted specialist agad, they have options depending sa exact situation, pero kailangan nila makita personally. Praying for you, mama, you're stronger than you know.
