"i am about to finish up my fifth pack of lo-loestrin.  lately i&#039;ve been noticing a weight gain, even though i have changed my diet and started working out 3-4 times a week.  i have gained about 10 lbs in the last 4 months and continue to gain 1lb per week.  at first i didn&#039;t think it could have anything to do with this pill, now i&#039;m starting to wonder.  my skin has been clearer and i have not had a period or bleeding at all since i started this pill.  but the weight gain is a big deal for me.  my breasts have gotten bigger and are a lot more tender.  mood swings have been tremendous, didn&#039;t notice a change in sex drive.  i think everyone is different and every birth control you take is going to affect each woman differently."
