Due to a varied colour of spottingI had an ultra sound Thursday it confirmed I am 7 weeks+ with a viable heart beat, I'm concerned as last night there was a lot of bright red blood passed then I remembered I didn't ask if my cervix was open, all I know is they couldn't find a reason for any bleeding. Could my cervix be open? At what point do I really panic and call out of hours doctor, any help would be great x
