Bso you will go by the 12 ofevery month as your one month mark so say you got pregnant july 12 your edd expected due date would be april 12 th but no foctor can pin point your exact due date thats impossible due to other situations that can occur in pregnancy that would call for er c section or premature labor or other but just be prepared around the date u recieved.
They count the first day of your last period as the first day of your pregnancy so they would class you as 5 weeks and 3 days. Congratulations x
