Bump shrunk?

Odd question, I know!

I’m 31 weeks, and when I woke up this morning my bump is considerably smaller. Even the husband noticed and commented on it!

With my first, my waters started leaking at 35+ weeks and he was born at 36 weeks... I also have a shortening cervix that we found starting at 20 and 24 weeks....

Anyone else notice their bump get smaller?? I realize it could just be his position... but with everything it makes me paranoid! (lol).
