Huh, suddenly overdue again?

Okay ladies, here I am again haha!

I can head out first thing tomorrow morning for a beautiful pregnancy test haha, but I just had to vent...

Our little boy is exactly 6 months old today and is still exclusively breastfed. Since my period came back right away and regularly just 6 weeks after giving birth, meaning I ovulated again, I took the mini-pill for about 3 months.

I stopped taking it again because it was just too much for me. I felt absolutely terrible on it, and my milk supply definitely took a huge hit... I got my period again just 3 days after stopping, didn't have much bleeding, it wasn't long but I did have cramps.
My libido was finally back (yayyy!) and we started using condoms.
But now... I'm already more than a week late. My supply suddenly dropped back down again since yesterday. And I've had period-like pains for a few days, so I expect it, but it just won't come...

Oh oh, what now... haha...
