My belly popped at about 13 weeks this time. With my other pregnancies it didn't happen until about 17-18 weeks. This is my 11th pregnancy so I guess things are pretty loose and free!!!!

What you are experiencing is probably bowel distension that occurs in early pregnancy due to the slowing down of bowel action caused by progesterone. It makes you bloated and full looking. Much as before your period.

Wishing you a healthy and happy pregnancy...
