6w1d- baby has a heartbeat! (YAY!) but the e.r Dr said the ultrasound showed "past bleeding"? around the area If I can remember it correctly. i asked if it was a tear and he said it was most likely nothing. didn't give any names as of what it's called... but put no strenuous activity until I see the o.b next week and he clears me. does anyone have experience or know what the heck that means?! Tia! never dealt with this before!
