Is it possible that the women period time delayed after sex. I had sex with my wife about two weak ago and according to her timing she should get period during these days,but she has not got period yet. We also used baby check ( test for pregnancy) and the result of test was negative. But it is about 3 days which passed from her period time but she has not got period. Is it usual?

I would assume you would be having sex with your wife, very often,?

No just having sex does not delay.

There is no reason at all to test yet, it is way, way too early.

Women can be a few days to more days late all the time, very common. She needs to be over 14 days late, before you start testing, the test needs to be first thing in the morning as soon as she wakes up
