      Have you called your doctor to discuss this further? It’s possible if you have an excess of stress in your life or have had other health issues or are exercising a lot that your cycle could be affected. Best wishes!

    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.

    • Profile photo of Megan KlayEditor Megan Klay says:

      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!

    wow same date my doctor told me

    This isn’t doing anything….?

  21. 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.

  22. 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.

  23. Profile photo of PortiaRatolo PortiaRatolo says:

    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

  24. 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?

  25. Profile photo of carlton carlton says:

    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!
