Hey guys how far pregnant am I if baby is measuring 3 millimetres
You need to see your doctor and have a dating scan done.
The gestational sac first appears at about 4 week’s gestational age, and grows at a rate of about 1 mm a day. Thus, a simple way to "date" an early pregnancy is to add the length of the foetus (in mm) to 6 weeks. Using this method, a foetal pole measuring 5 mm would have a gestational age of 6 weeks and 5 days. Considering your report I think your gestational age is about 4-5 weeks. Hope you find this information useful. At the last doctor can tell exactly what you want to know. But these measurements are very rough. You won't normally know the exact day and the age of the pregnancy is only an estimate based on your last menstrual period.
