Hmm....I personally started on the NuvaRing two months ago but then I missed my period the first month after and it totally freaked me out and the thought of being pregnant led to a huge crisis situation....long story.

I'm off it now and having a much heavier period so that could be related. Anything with hormones can mess with the woman's mood. I know Ortho Tri-Cyclen made me really *****y, while other pills were okay (back in college).

If she wants b/c without hormones the only real option is the copper IUD. It's good for 10 years and some women love it but some get heavier periods.
