AF symptoms or something else?

Lately I've been feeling really blah. Moody, aching lower back, no interest in doing any of the things I used to enjoy. Of course, I also don't have any time to do those things.... so I think that might be the problem with that one.

I was wondering if AF might be about to make her return. I feel tearful but don't even have the energy to cry, thanks to a really really LONG stint of terrible sleep. DS2 wakes hourly at least, day and night. I bedshare and bf on demand but I'm still wiped out, emotionally and physically. It doesn't help that he's been teething FOREVER and still has no teeth. My nipples are feeling kinda raw. DS1 wakes frequently too, and is starting to drop his daytime sleep. (Oh god no!)

So my question is: how did you feel before AF returned post baby? When did it return? Did you have normal symptoms or was it like BAM.. there she is? I FF DS1 so AF pretty much returned 8 weeks after his birth. Or is all this not AF related at all and I'm sinking into depression? I've felt this way for a few weeks and I can't seem to get my groove back. Lack of support doesn't help.

I can't think straight to make this post pleasant and sensible to read, so I'll just leave it at that!

Thanks in advance :)
