We as a couple are planning for a family for last 3 to 4 months, I am 33 while my wife is 30. However we are not sure if our approach is in the right direction or not. We have been following the ovulation cycle carefully, and every time we feel this is the time but the only thing happens is the periods get delayed by 3 or 4 days and we are back to zero. Not able to understand where the problem lies, inspite of following all the processes properly. Please guide as to what should be our approach now in this case.
