The only time it does sting is when people take it for granted. And if I say anything about how blessed they are just to have a baby/be pregnant, then they proceed to tell me that I don't know what it is like to be in that situation and that I will feel the same when when I am.
Um, ouch! I would give anything to be in that situation. Some times if baffles me the things I have put my body through to be in that situation. Boatloads of bloodwork, ultrasound, MRI, x rays, SURGERY, drugs, spending every spare dollar on treatments, month after month of charting, money spent on OPKS. I have not done all that stuff so that I can gripe about everyday challenges with a baby.
It goes both ways. I may not know what it is like to be a mother, but most don't know what it is like to deal with infertility either.
So please, don't assume I will feel the same way as you. One of the benefits of infertility is that I will be able to find joy in the 40+ weeks of pregnancy, screaming babies, sleepless nights and blow out diapers that a lot of people take for granted.
