as per my lmp due date is 11 march but as per first ultrasound edd is 26 march what date should be considered for delivery if I want to opt for c section

A. Mam it is a C-section then I would advise you to complete your term of 39 weeks take the last period date into consideration and calculate 39 weeks on a calendar she’ll have a better understanding so whatever estimated delivery date is close to that go ahead with that complete your term even if it is a C-section
