The same thing happened to me, honestly. When I first started BC about five years or so ago, I had a three or so week bleed. It was very painful in the beginning, but I believe that it just takes time for the body to adjust to the extra hormones. Though I would recommend seeing your doctor,it could very well be you still adjusting to the new hormone levels.
hmmm, I am very stressed, but I think I eat pretty healthy....I am on birth control which is a prescription drug, no new sexual activity, and I drink water like a horse, so I know that's not the problem. I am going to have to talk to the gyno soon! thank you soo much!
Please note that various things can cause irregular periods such as stress, anorexia, bulimia, poor diet or dietary problems (such as too much consumption of phytoestrogens such as beans, or too much consumption of bread or flour products or too much consumption of soda pop or potato chips or other acid foods or junk foods in the diet), prescription drugs, new sexual activity, or thyroid problems can also cause irregular periods, not enough consumption of water daily could also be an issue ... see http://www.menstruation.com.au/periodpages/irregular.html for more info.
Also, soy consumption in some cases can cause irregular periods....see the following two articles for more explanation:

Also, leaky gut syndrome could cause irregular periods. There is a book by Dr. John Pagano called "One Cause, Many Ailments: Leaky Gut Syndrome" that is available at Amazon.com
Also, if you have fibroids, that could cause irregular or very heavy periods. See:
If you have fibroids, ask your doctor about a product called fibrovan to see if that is a possibility for you. See http://www.fibrovan.com/index.html for more info on Fibrovan or see if the doctor has other ideas about how to help get your periods back to normal again. As far as I know there have been no formal studies pertaining to Fibrovan although anecdotal reports have been encouraging. Still, talk to your doctor to get your doctor's opinion first.
Finally, there is a lot of alternative medicine literature out there. The Cayce readings would be something you could read or the information on colonics and castor oil packs and various things also might be interesting reading. For example, pertaining to your particular concerns about excessive menstrual flow --the following webpages might be interesting reading for you:

The above mentioned information should not be taken as a substitute for talking with your doctor. Always talk to your doctor first about any health concerns or questions you have.
