I take the pill that way. I'll go 3-5 packages where I dont take the inactive pills, and then I'll start my period before the 6th package. It's quite nice to be able to scedule my period like that, and I know many women who do the same thing. You should start your period sometime, so dont take it like that for too long, so your body can flush itself every once in awhile, but it's perfectly safe. My doctor actually recommended it to me when I asked her to put me on this pill thats supposed to surpress your period for 4 months. She told me that she heard a lot of complaints about the side effects of that pill, then began to explain how I could do the exact same thing with the birth control pills I have now. So, to answer your question, yes, its perfectly fine for you to do that. I've been doing it since I was 19 (I'm 22 now), and I've had no bad side effects. In fact, the only side effect that I've noticed is that my breast start to get larger after the 2nd pack.
And as to the "does that make me too unfemale" comment, what do you mean by that?
There's nothing "unfemale" about not wanting your period LOL. No woman enjoys thier period.
