So according to my calculations I'm 6wks 4 days pregnant, I've been having cramping for 2wks started spotting pinkish looking discharge 3 days ago and then it turned into brown, and now its I'm just bleeding its really light.. Went to the ER according to the ultrasound I'm 5 wks 4 days, they weren't able to say what was wrong they only said my cervix is closed and they didn't know what was wrong. Should I be worried??? Help
