Oh NattyFred, you poor thing.
I think I got a big surge of grumpy hormones for a while there. Everything annoyed me, even DP who is one of the most non-annoying people I've ever met. He was so sweet he said he could put up with the grumpy hormones until the baby arrived. But after a few weeks it seems to have cleared up. Here's hoping your grumpy hormones fade away soon too.
However, the grumpy hormones disappeared at the same time the fatigue set in again. So I'm off to bed!
