I have had two periods that were very light and short since having my son almost 19 months ago. When I got it back the first time I was so excited because we could start TTC. It was due again 2 days ago and still hasn't shown and all BFNs. All I can figure is it's gone away again (because I'm still BF). I wish there was something I could take to encourage it to come back and make it more consistent. I've never had to put much effort into TTC. We decided to try and it happened within a month or two tops. Now I can't even get a consistent cycle! Ugh!
