My shape changes but I stay the same for 2 weeks. Boobs are slightly smaller as I've needed to get new bras but I have started to get an hour glass figure (if I wear my sheepdog bra - it rounds them up and points them in the right direction- ll! instead of looking like a beach ball. (Worrying resemblance to violet Beauregard in Charlie and the chocolate factory when she chews the gum and swells up - wasn't blue though!)
