Stopping birth control ? :/

Elizabeth • 28 & happy.
So I have been on birth control for just about 11 years, not including the 3 or so months I stopped taking it. That's quite some time. From the time I turned 13, and now I am 24. I don't want to be on it at all. I feel as if it has completely changed me and killed my libido, and I want it back. I started on pills, then switched to the patch, then to pills, then do the depo shot and now back to pills. Now my question is, if I do quit taking the pills all together, what would be my chances of getting pregnant? My boyfriend and I are not ttc. I just want to feel sexually excited again. Sorry for the long rant, any advice would be awesome! Thank you, ladies! :)
