    Hi. i’d like to ask if how many week/s is my tummy: the 1st day of my last period was march 28, 2017. our contact starts on april 13, 2017. Until now i don’t have my period.

    • Profile photo of Megan KlayEditor Megan Klay says:

      Hi Mae – Input the first day of your last period and the average number of days between your periods (last day of one until the first day of the one following) to determine when you likely ovulated. Then conception could have occurred anywhere between three days prior and three days after. Congratulations!

    Hello so question. I am almost 25 weeks I am due 8.19.17. Could it be possible I conceived 12.2.16? Doctors say I conceived around nov 25th but I don’t know how accurate they are. I can’t recall last period either

    Hello, I’m not sure what to say. okay I’m 46 years old I have a 26 year old son who has 4 kids of his own and i also have a 24 year old daughter she don’t have any kids yet. and to my Surprise BIG surprise I’m going to have a baby my grand kids will be older then my new born baby who will be born in September this year. well to say that i still cant believe I’m going to have a baby at my age. I don’t know if it is to soon to be scared to have this baby or if I’m just nerves to be pregnant at my age i pray it will go good and the baby will be born healthy i can’t wait to know if I’m having a girl or boy. well like i said I’m not sure what to say I’m still trying to absorb all of this.

      Congratulations, Lorraine! Things like this certainly do happen, so you won’t be alone out there! I would just make sure you make all of your prenatal appointments, eat healthily, and continue with safe exercise. At least you’re experienced and baby will be well cared for! Take care of yourself, mama!

    The doc changed my due date from 8/17/2016 to 8/30/2016. How do I see the development of the baby now?

    This isn’t doing anything….?

  11. Profile photo of Bethany Bethany says:

    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?

    • Profile photo of Nat Nat says:

      Depends on how you doctor calculates it, most do it from last menstrual cycle and some do it from date of conception the difference is two weeks. hope that helps.

  12. Profile photo of San San says:

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

    • Profile photo of Nat Nat says:

      It’s had to predict exactly but my guess is your luteal phase is a bit longer then you had it set for, that would account for the difference.

    thank you very much i got to know my conception date as the dates are so close to the one the docter gave me iam so grateful for being part of the everyday family and iam looking foward to learning more in this jorney

  14. Profile photo of Tesha Tesha says:

    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

    • Profile photo of Megan KlayEditor Megan Klay says:

      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?

  17. Profile photo of dianetira dianetira says:

    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.
