has anyone else popped over night ???

I literally popped overnight! At 22 weeks I had a small bump then one day during my 23rd week I got bloated, then went to sleep, just to wake and and find that I wasn't bloated at all and that my stomach was just actually that size now! Lol 
Anyone else pop overnight?? 
This is my 2nd and she is measuring a week ahead, so maybe that has something to do with it. Lol
