My mom was very open too, but I'm a very shy person, and never talked to her about my personal life with her. Of course, I hadn't even kissed a guy at 15, then hated my first kiss and it took a whole year to be brave enough to try again...so I'm not quite in the same situation as this girl.
But I find it REALLY obnoxious that you're calling this woman whacko, etc, for not allowing birth control pills (have you ever READ the package inserts of all the complications that can happen with them, or LISTENED to the commercials where they list all the dangers?) or using western medications for cramps...I don't do those either, but am not "whacko". I just don't like using freaky extrinsic hormones to artificially control my body...doesn't seems like it's going to turn out well for us, putting all that stuff into our bodies (and, sadly, our waters which now have measurable hormones in them).
I don't feel you had a place in this situation. If a 16 year old girl came to me with this, I couldn't get involved. It's just not your place.
Also, and this was my stance as a teenager and young adult as well...if I wasn't mature enough to figure these things out for myself, to make an appointment and have the appointment to talk to someone about condoms and pills and whatnot...I wasn't mature enough to have a boy in that same area as a gyno would be. I also stayed away from sex until I knew I could make a decision about a pregnancy....meant I was 21 when I did have sex!
So if she's not mature enough to find this info on her own, she really should think about waiting to do these things until she IS mature enough.
That's likely as far as I would have gone in conversation with her...but there's NO way I would have gone to a health department to get info for her.
And for ANYONE surprised about a woman not knowing about her cycle, should read the anecdotes in Taking Charge of Your Fertility...there are MANY women who don't understand their bodies...
