Subchorionic bleed

I had an ultrasound at 6 wks 2 days and they found a small bleed in my uterus. Baby was ok. Fast forward to today. 8 weeks 2 days and the bleed is bigger but baby is still ok and wiggling about with a health bpm of 141. They want me back in 2 weeks for a repeat ultrasound to make sure it's not getting even bigger. Is my baby in danger? If it gets to big will I lose the baby? I was gonna announce litterally today but now I'm not so sure. Maybe i should just in case something goes wrong and I need support? I dont know i guess I just need some insight. To hear someone else's story.
