I want to scream

I want to cry.  I hate TTC.  When someone says TTC is the fun part...infertility may not be an issue for them.  I really want to have a 3rd...I am absolutely 100% blessed to have my 2!  But why can't I now conceive again?!?  I understand the only way to know for sure is to go get checked out.  To tell the truth I am ashamed.  I can't have kids naturally, so scheduled c-section it is....and now I can't get pregnant!  It's frustrating!  I also feel wrong going in as some women can't have kids at all so why should I be there when I already have 2.  Ugh.  It's been a little over a year and a half and I just wanted to let it out.
