    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.

    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

    • Avatar 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!

  17. This says October 15th and the ultrasound tech said October 30th. Uh, I’m going with the 15th. The sooner the better!

      Hi there – If you know the first day of your last menstrual period, and your average cycle length. This due date calculator should be able to give you a pretty accurate estimation. Best wishes!

    Havent had my first dr appt yet but judging from my LMP and using the due date calculator im about 7 weeks. However, my periods arent always to the day, usually withing the week though. I have a feeling I may be a little further along, perhaps had a period while pregnant?? Ive had issues with acne and constipation the month before we found out we’re expecting and that is abnormal for me; especially considering I took probiotics dforor about 3 weeks and very little BM’s. Oh and I started gaining weight without a change in diet or habbits so those are my reasons I believe I May be further along. My first dr appt is the 7 so pray all is well…or for twins :)

    I honestly thought my cycle was off, because of the stress I was undergoing. However, I was wrong, but I am happy I was able to find out at an early stage, so I can take all proper precautions.

    My fiance and I have been together in and off for 5 years. We have a daughter and he has another daughter. I am currently expecting my second child with him however, he recently got out of prison after doing an 18 month bid. He got out about nine weeks ago, I’m eleven weeks pregnant. The baby is his for certain but he’s having trouble understanding how pregnancy works. I explained it many times. Any suggestions.

      Take him to appt let doctor explain.. that helped my husband. Also the magazine showing baby growth from egg to fertialization all helped his comprhension

    • Avatar of cassie cassie says:

      They count the weeks starting the first day of your last period even though you arent technically pregnant yet, they count the time where its Just the fertile time when the sperm has a better chance of getting you pregnant. They Say your so many weeks pregnant but there isnt an embryo until 2-3 weeks later after the sperm has fertilized the egg during the fertile time (which is the 2-3 weeks after the first day of your last period) Basically they count your period and the time in between until his sperm makes everyhing happen :) Maybe if he reads this he can understand??
