UT and birth control

Just out of curiosity. How does a women do UT if she takes Birth control pills. I have read that you can't do UT if you are on medication. Also, I imagine you could really mess up your cycle if you were doing UT (drinking what you took a couple days earlier.) I would like to hear from an experienced UT women. Also explain, if you don't mind, how you do it when you are on your period.

The reason I ask is because I have read testimonials from women on another web site. I am a man so this doesn't apply to me, but I want to know. I would like my significant other to benifit from this if it works. Finally, can a women realistically be sexually active (on birth control) and do UT. Tweet
