Uy mama, I totally understand the worry, first time moms talaga, everything feels scary! Pero honestly, a lot of mum friends ko had subchorionic hemorrhages during pregnancy and most of them resolved on their own, especially kung ganyan kalaki lang, your OB will monitor you closely lang talaga. Best thing you can do is follow your doctor's advice, take it easy, and attend your checkups regularly; don't hesitate to reach out to your doctor anytime kung may bagong symptoms or bleeding, okay? Sending you positive thoughts, mama, most cases turn out fine!
