Subchorionic?

Amber • Mom of 3 boys🧒 Alaina Renee😇 Lucy Annalise🤰🌈

I was diagnosed with a small subchorionic last night. The baby is also measuring 6 weeks which is what I am with a heart rate of 130 which she said was kinda low. What do I do now until I see my OB Wednesday? Bed rest? I never had this with my other pregnancies.
