"i will be finishing my first pack next week.  my only complaint so far is that i&#039;ve had a lot of mid cycle bleeding.  this is the 10th day of my period, with no signs of slowing down.  i know that it can take awhile for your body to adjust to a new birth control pill, so i&#039;m going to stick with it for a few months.  other than the bleeding, i&#039;ve had mild breast tenderness and some bloating. like i said, it is only my first pack, so hopefully these side effects are short term."
