We got married on may13th 2014. Before that we had sex on April 26th. My wife’s last period’s starting day is April 16th. 2days back we took pregnancy test & it is confirmed that she is pregnant about 6weeks. Doctors calculated the first day of the last period. But we told doctor that we got married on April 26th as we were shy to tell the truth.
Nw my question is can we tell our parents & relatives that my wife is pregnant for 6weeks? Wil they come to know the truth by counting the dates? Or is it medically possible that the pregnancy calculation from april16th for the first intercourse done on may13th (lie) ?
Doctors given the due date 21st jan 2015. Is it medically possible that the couple got married on may13th (last period was started on april16th) & giving birth to a baby on jan21st?

Please suggest us hw to tackle this…

Just tell the truth... why the big deal... they are going to figure it out anyway.

A month and a half premature baby would not be going home with mom like a full term one would. Most adults would know this.

Telling everyone a lie will be magnitudes worse than the truth. You are both adults... show it.

If it is important that the child is conceived within wedlock and that the bride, and maybe the groom, was virginal at the time of the wedding than you're kind of in trouble. Anyone will put the numbers together and see that it happened before the wedding. The child will be born within wedlock and you wouldn't have known that she's pregnant going into the wedding.

It is a bit of a problem but honestly you shouldn't be telling your family and parents that you're pregnant until the end of the first trimester. Just in case something happens in the early pregnancy. I wouldn't worry about it, it isn't really any of your family's concern when the child was conceived.

I agree with Craven, no one's business but your own and your new wife. Congratulations and I hope she has a smooth pregnancy.

If she gives birth in Jan, there are people who will count back and gossip. There is nothing you can do about it. But the date of conception is your business alone. I would not be too specific just tell relatives the doctors are estimating a January due date. Calculating due dates is an estimate.

If you are an Indian, I can understand your problem, there the values and cultures are different. And I know, If they will come to know that you had sex before your marriage even though you were engaged it's a huge thing for them, problem may cause not only for you, but a lot more for your wife why I am saying that you know it (if you are an Indian), for a small decisions also they concerns with family,a couple go through a lots of pressure by the Family and even society over there :/,(still not every families are like that) . But I'll go with what others have said, a small lie can cause you to lie more in future. So better, you just say them the truth, here you can do one thing, just plan it up how you going to approach them, for example- you say it when they are in a good mood and something like that. I know, that will not change the situation but can lower the probability of their reaction towards this subject. And remember your wife needs more support in this situation. I can understand how you feel.
All the best! :)
