  • They don't count it from the day you had sex, they count it from the date of your last menstrual period.
    Try again.

  • Yep the calculation is from last period. That is why so many are off by a week or two. If you know when you had sex and conceived couldn't you just add 9 months?? But know that the date will be different from what the doc says.

  • I think Jan 22nd is the due date. Count back 3 months from date of first day of last period and add 7 days. LOL. That's the way we did it in the old days.

  • To find your range, enter the first day of your last menstrual period in the form below. Click on the calendar icon to select a date from a calendar.    We calculate your due date as: Jan, 20 2014

  • Based off the LMP conception would occur on or around April 29th. So chances are slim because most of the sperm from the 26th will have died off. Due date would be January 20th. I used to work an OB office and I still have the wheel they use for calculating this. LOL

  • It depends on when you ovulate. If, for argument's sake, you ovulated on cycle day 14 (in this case April 28th) you would "conceive" on that day with the sperm that were still hanging around from when you had sex on the 26th. Although you very well could ovulate earlier or later than the 28th, every woman and every cycle is different. If you conceived on the 28th, however, your due date would be 38 weeks after that - January 19th, 2014. (About 40 weeks after the first day of your last period - which is usually what they go off of even though it's less accurate, since most women don't track ovulation.)
