My daughter took a clear blue test 3 weeks ago showing 2-3 weeks pregnant. Her periods have not been at all regular so can not confirm when she had a last period. She went for an early pregnancy scan yesterday which showed the sac and yolk and a little dot they said but they couldn’t confirm an embryo or nub? My daughter is now worried incase she has miscarried. The midwife says to wait for her regular scan in 5 weeks time but my thoughts are should she have another reassurance scan in a couple of weeks as 5 weeks is a long time to wait.
