Aww mama, I'm sorry you're going through this, that must be so scary, especially ngayon pa lang ang pregnancy mo! A few of my mum friends had subchorionic bleeds too and they were on the same meds, kaya at least may peace of mind na alam mo na may protocol na ang doctor mo; just make sure you rest talaga and avoid heavy lifting or strenuous activity, okay? The cramping and spotting can be stressful but your OB is already on top of it with the Duphaston and folic acid, follow up lang as scheduled and don't hesitate to call agad kung may heavy bleeding or severe pain. Thinking of you, mama, marami nang successful pregnancies kahit may SCH so stay positive!
