Hi Trish.
The worst part of TTC is all this waiting and not knowing. I totally understand your hesitation to talk about this, as i am exactly the same.
I would be guessing that the fact that your cycles are not back to normal since stopping BF'ing combined with the recent m/c is messing with your cycle.

I have really early preg symptoms just as you describe. Kind of feels like AF might be coming. So you never know.
Like you have said, all you can do really is wait. Well i guess you could go and get a blood test to see what your HCG levels are doing, but that is not really going to change much.
If you are not UTD, then fingers crossed your cycles settle down. But hopefully you are UTD and it was just a wierd cycle.

Sounds like a bit of a rough patch with the m/c and the little man weaning. Hope you are managing to rest up and are doing ok.
