More giggling while pregnant?

I’m a pretty serious person and once I was 17 I didn’t really laugh that much past that age and it’s especially odd of me finding anything hysterical. But now I’m 21 and 32 wk 4 d pregnant; I find myself cracking up at the weirdest things (even my boyfriend says it wasn’t that funny) I just can’t help it lol I’m not sure if pregnancy has this affect on people but I’m grateful I got my laugh back. Now I just want to watch wipe out videos and laugh lol can anyone relate?
