anyone ttc#2 and in 20s??

so my dh and I are in our 20s and ttc #2. we have been getting "advice" on if we should have #2. some people are asking if were going to have another, some say so when's the next one and others say it too early/soon. weather its too soon because of our age and or the age or our first. when people bring it up it kills me because we want another and its just not happening.

I guess part of me just wants to know I'm not alone.
