Crazy hormones!

Yo
So during my induction with my first, after many hours of pain...I started laughing and crying (at the same time hysterically), it was quite hilarious. This pregnancy that has happened a few times (after sex😝...poor hubby). Tonight after dinner, hubby and daughter started singing and dancing together, she soon started copying all his moves (she's 2yo) and they were making me laugh soooo much I was again hysterically laughing and crying at the same time...I also started leaking from my right breast for the first time this pregnancy. Anyone else laugh and cry at the same time for no reason or for normally happy reasons?
