Well, some of the health risks are blood clotting, and higher risk of cancer and the reason for this (so I heard from a doctor) is that this medcation puts a lot more estrogen in your body than the pill and estrogen causes clotting and cancer (i believe thats correct). Since the pill is taking daily, the estrogen is monitored, but the patch is left on you day after day, so the hormones aren't controlled as they release into your body. As for the price of it, I know that without insurance, the patch is about 90.00 (a month supply) but my insurance made me pay 30.00 (which I think is a lot). You could probably get it a planned parent hood or something for a lot cheaper or even for free, but I really think you should discuss the risks with your doctor first, because I didn't even know that I had a higher risk of cancer until 3 years of being on the patch. If you can remember the pill, then I really reccomend that, but maybe you should do something non-hormonal (since maybe you are breast feeding) like an iud which is a copper implant that is simply put in by your obgyn. I believe it is place in your cervix and will be effective for up to 5 years, and if you want to get pregnant again, then just get it removed. I know there are a lot of options out there for birth control, but I really think you should think twice about the patch, becuase like I said, there are soooooo many health risks. I hope this helped!!
