I'm pregnant how do i find out what's my due date ! my last cycle was january 4 nd i never see it yet but i took four pregnancy test ?

October: The due date by the last menstrual period is calculated based on the first day of the last period. If january 4 was the first day of your last period then the due date based on that would be october 11, 2014. I am assuming that the pregnancy tests you took were positive.

Try next week!: It's only been a week after your expected period. Try again next or your period might just come because it was late for some reason -that happens. Do you have regular 28 day cycles? If not consult your doctor.
