U likely 4 weeks preggy based on last period. U need to decide which gynae to have ur check. Appt may need 1-2 weeks in advance. By then 5-6 weeks. I guess by time of 6 weeks is a gd time for 1st scan. If u have doubt, u call check directly with ur preferred gynae clinic. Do join November / Decemeber MTB (Mother to be) forum here.
