Hmm....if you were bleeding that much, have you considered continuous birth control? Like Seasonale? That way you'd only have a period once every three months.

Has the spotting/bleeding gotten better at all since last month? If so, then I'd suggest maybe waiting one more month to see if it seems to be continually improving. But if you start bleeding really heavily (going through a pad or tampon in an hour) then DEFINITELY go to your doctor. You could always go now and ask for a pill with higher progestin in it, like Desogen or Demulen. Although as I said in my previous post it takes the body three to six months (generally three) to get used to any given birth control pill, so even if you change you might have breakthrough bleeding.
