Why do some women on Glow bash on others who get pregnant quickly?

I have seen so many post and/or comments of women who have been trying to conceive for a year or longer and seem to be upset with women who make comments like "have been trying since..." And to them it isn't long being that they have been trying longer but honestly what is the need to make someone feel like they have no right to complain unless they've been doing it for a certain amount of time?
