The calm before the storm

As
I've heard this phrase but I never knew it was a thing. I have been soooo miserable up until  today. I woke up this morning feeling content. I wasn't in too much pain, but I'm just... Calm. Relaxed. I could be pregnant for 3 more years and not care... That's the mood I'm in. I find this very strange as generally I 100% hate pregnancy. Am I broken?
