Saying this to a women struggling with infertility is not something she wants to hear. It takes a couple under the age of 35 on average about 6-12 months to concieve naturally. 

Infertility is “a disease of the reproductive system defined by the failure to achieve a clinical pregnancy after 12 months or more of regular unprotected sexual intercourse.

There could be so many reason why a couple are struggling to concieve. So telling them to just relax and it will happen, is basically ignoring the fact that there very well could be a problem, and in most cases there is. It is important to relax, I am not ignoring that, but please think before you say that comment to someone suffering with infertility. 

It is natural to ask someone do you want children in the future? I was brought up as a Christian (I no longer practice) and family plays a very important part in the religion. I have been asked on several occasions, do I want to have children? I was even told by a leader in the church that I ought to start thinking about settling down and starting a family of my own. I am ok with people asking me if I want children, or do I have children, but I do not like the assumptions that people make. People need to be aware of the many reasons why someone may not have children.
