I started spotting on Friday and went to the ER on Sunday (I was out of town for the weekend). Had an ultrasound which showed a baby measuring around 5w4d and a heartbeat. However, also saw a subchorionic hemorrhage which was the cause of the bleeding. The darn thing has apparently pushed part of the placenta off the wall so it's been termed a "threatened miscarriage". I was so happy to see a baby and a heartbeat, but so worried that this will end poorly.
I had a bleed at 7 weeks with my first pregnancy and all turned out fine, but they never saw a hemorrhage and definitely nothing that affected the placenta so this is more worrisome.
I will likely have a follow up ultrasound in a week or two.
