Hi Tammy,
I know this is an older post, but I wanted to answer this, at least give you my input on it.
If you are aware that that your daughter is sexually active, to me it would seem you are only in denial if you don't suggest for her to go on birth control. I do understand what you are thinking, but I don't think its the best choice. Of course my first choice would to be to talk to her about the choice she has made, and the fact that she is indeed sinning against God in this act. But if she is not receptive to this, and I would suspect she wouldn't be, then I would take her to get birth control and also inform her about the dangers of AIDS and other STD's. There are so many STD's out there, she better protect herself from those. HPV is prevailant out there. So much so, that they are trying to get a mandatory Vaccine for girls as young as 9 in a state local to us. That just makes me ill.
Anyway, I hope that your daughter somehow comes back around, but if not, keep her as safe as you can, and inform her.
We as Christians NEED to inform our kids and not just hope nothing happens.
