Sir, my wife last period is on 11th july night (10 pm) and it lasts for 4 days .normally her period is 30-33 days ,we are newly married on 14th july but first sex (unprotected) on 29 th july (11 pm) and for next three days we have unprotected sex. But now on 13 th aug no signs of period is coming. Is my wife is pregnant ,when should we go for test. Previous period is also delayed for 3 days. We do not want a child now. Or just wait for another week.
