Ok, I actually asked my ob about this Why am I embarressed ... because everytime I ask my ob about something similar ... his answer usually has something to do with my bowels

You describe it so perfectly. My recent three were all on Sunday afternoon (hanging washing is not fun when this happens)

My ob said that it has to do with pressure of wind/gas or if you need to have a bowel movement. So I would guess that you have a bit of constipation, right?? Because that is my problem atm. Try upping your fibre and fluid intake and .... try and f@rt as often as possible!!
