question for the ladies re: the pill

Hi i have just recently come off the contraceptive pill and am wondering what i should expect, i used to skip my period alot on it too. i have been off it for about 3 weeks now and am feeling really bloated. havent had any break outs which is good because i hear you can once you go off. could i epect a bit of water weight loss soon or weight gain/loss??? any info would be a great help thankyou
