If i was 6 weeks on auguest 3oth when did i conceive? also ..what would of been my regular due date?

Gestational age: If you were "6 weeks pregnant" on August 30th, by standard conventions, that means your last period was 6 weeks before August 30th, or July 19th. So, if you had a period on July 19th, then your date of conception was approximately two weeks later, or August 2nd. Based on all of this, your due date should have been April 25th, which is 40 weeks after your last period, or 38 weeks after conception.
