41wks pregnant, was due 4/18/14. conception calc says conceived 7/26-7/28. but, any chance i actually conceived in early to mid june instead?

Possible, However..: I suppose it's possible you conceived earlier than is being calculated, but i would also go by what your ultrasounds are saying as well. The size of the baby helps us date a pregnancy and figure out approximately how far along a pregnancy is and the due date, but sometimes this can be off a little bit. I am a bit doubtful that your scan would show a baby 41 weeks big if conceived a month earlier.
