11 and 13weeks seems abit late imo. the first dating scan should be around 7–8w, so that we know for sure there is fetal heartbeat and that the embryo is deposit in the right place.. Also for first pregnancy, u will have to take antenatal blood test for thalassemia, blood count, platelets etc to scan at first appt..but i heard if you chose for a popular gynae, it will be difficult to get a earlier appt.. even the Fetal scan centre is fully booked that my FT scan will be done by the gynae instead…
