They can give you an ultrasound to get a better estimate but they will never be able to tell you the exact day you concieved.
There is really no way to know the exact day you conceived.Sperm can stay in you for a few days and there is no way of knowing if it got to the egg the first day you had sex or a few days later they pretty much just make a close guess.
Did you have sex the 8th - 13th? Sperm can live inside you 24 to 48 hrs before the egg is released during ovulation.
the apps that I'm using are telling me either November 7th or 8th , Is the day I conceived. This is my 1st pregnancy and I don't have a Doctor appointment until January 11th . We just want to know the exact day .
I am indeed pregnant but is it possible to get pregnant before your most fertile days ?
So what is your question?
