Hi Sherrie,
I'm new here too with similar issues! Is there a TTC while breastfeeding area on this board? I saw one but after signing in I can't find it. Plus the post were a few years old, perhaps those ladies are busy chasing after their new little ones. :-)
Same boat with you - My son is 16 months and still no cycle yet. We cosleep and he nurses, or comfort suckles about 3-4 times a night. I can reroute him some days with other fun activities, however on those nights he makes up for it by nursing every two hours.
So wierd that some of my mommy friends nurse just as often and have had a cycle return already. I dont want to wean him completely, as if that was even possible right now.

I adore nursing, and hope to get pregnant while still cuddling and nursing the little one.
I started taking Nature's Way Vitex 3x a day. I read on Kellymom that it could be helpful for those still nursing that wish to get pregnant.
