Bleeding 8 weeks 5 days

I went to see my obgyn as soon as I found out I was bleeding. So scared to lose my baby. My obgyn said it is a subchronic hemorrhage. Baby is doing good, still have a strong heart beat. So I was relieved.. did this happen to anyone? Even though I saw the heartbeat, I am still scared! I have another follow up ultrasound in 2 weeks.
