At 6 weeks 3 days. Last week I had an ultrasound done that measured 5 weeks 3 days. The gestational sac is bigger this week, but still no baby or heartbeat. Doc gave me the options to have a natural miscarriage, have a D&C or have another ultrasound next Thursday at 7 weeks 2 days in hopes something grows between the time frame. I had bled some brown last night and had a clot the size of the head of a nail if even that big as well as no cramping. I am not bleeding today. Is there still a chance this could be a false miscarriage and baby is just takin longer to grow?
