Rant away and welcome!! I think so many of us could have written your post and know exactly how you feel!!!!! I can tell you first off my success story from a few years back - was nursing my little guy for 16 months before AF came back (with a little push) - well past when I thought I would still be BF'ing but loved it so much more then I ever anticipated and was totally not willing to give it up to conceive......fast forward to when he was 21 months old and got a BFP while still night nursing and day nursing many times in a 24 hour period........he and his little brother are 2 1/2 years apart and it is a lovely age gap. #1 loves his baby brother most of the time, is very helpful with him, they are starting to play together, hold hands in the car, and when #2 sees his big brother he goes wild - smiles and toddles over to hug him. It melts my heart to see them together -so don't worry about the age gap - there is a lot to be said about letting your little one be the baby for a bit longer and skipping the whole 2 under 2 thing!
That said, I know you want to get things on track - SO - check out our TTC Facts folder in Mommy Talk section, get yourself some cheap OPK's off the internet, get yourself a Basal thermometer and start temping/charting, get yourself on a Bcomplex vitamin and join us for the journey. You are already ahead of the game if you are now seeing Af back - your first few cycles might be a bit longer then you like, but the b vitamin might help tighten them up (vitex would probably help that too) ........if you can night wean a little bit too, that would likely help your situation.
Any questions, please ask and don't get frustrated just yet - I am sure you will see that BFP very soon.
(SOrry my post is so scattered but baby is about to wake up and I have to run!!!)
