    Well this is pretty accurate…it was only one day off on the conception date. It was the 10th of april, and it said the 11th…but our Dr said the due date is Jan 15th but this told us the 1st…is this right? how can the conception date be one day off but the due date be a whole 2 weeks different?

    Based on my last cycle I would have conceived on May 14th but I didn’t have sex until May 16th…..is this accurate?

    I conceived in late May, but this calculation says June 20th. I also started using birth controls after I had sex in May can that throw off my conception date and due date?

    Hi my name is Tiffany I don’t know the exact conception date of my baby because I breastfeed my first son until he was 2 1\2 I found out I was pregnant when I was four months I am due in march how do I figure out my conception date if I haven’t had a period for two years

      Hi Tiffany – Your doctor should be able to provide you with this easy enough if they’ve been able to give you a due date, they’ll at least have an estimate of when you conceived. Just ask them at your next appointment. Congrats!

    Hi- I had my first day of my period November 17th and have slept with my boyfriend regularly, I had made a mistake and had sex with another man on December 18th and I have a 28 day cycle what are the chances of this not being my boyfriends baby?

    This was kind of accurate but my doctor say July 11th but this says July 5th.It was only 1 day off on my conception date.

    This is very close to the due date my doctor gave me it said July 5th and the doctor said July 11th. It was only 1 day off on the conceptio

    Hi everyone, I am new to this website and recently found out I am expecting my first child! My doctor says my due date is July 12, 2015 and so far all the due date calculators have been telling me the same thing. Hopefully both doctor and calculator are correct.

      Wow…. I assume we are nearly going to share our kids birthday. This is my first bundle of joy as well. My due date is the 14th of July. I’m curious to see what gender I’m carrying, be blessed and may we both have a wonderful and successful pregnancy and delivery.

  16. Profile photo of Ulyssa Ulyssa says:

    My doctor said my due date would be Sept. 28, 2014, the due date calculator predicted Sept. 23, 2014 and my baby was actually born Sept. 21, 2014. The calculator was closer than the doctor was XP

    If my last menstrual period was March 26, 2014 why’s my due date January 9, 2015?? Please help I think my doctor is so off and he’s really due dec/31st

    • Profile photo of Megan KlayEditor Megan Klay says:

      Hi BrieAnna – I would just give your doctor’s office a call or ask them to breakdown the dates for you at your next visit. You can mention that you’ve used an online calculator and it gives you a different due date and say you’re just hoping for some clarification. Congrats by the way!
