group menstruation while on HBC?

[jenn-possible.livejournal.com]

I have searched the internet all over for this, but I can't find anything about it.

I have been on the pill for about six years and have lived with female roommates since September. For the first few months, my period was out of wack from moving to grad school, and since I've come back from winter break, I've been having my roommates' period and mine!

Basically, I have breakthrough bleeding when my roommates are menstruating (all at the same time, of course) and then my own period during my pill's "off week." This happened a few years ago when I was an undergraduate, and I actually quit the pill for a few months to sync up with my roommates' periods. When I went to the Women's Health Center last week, the nurses were amazed that anyone could "group menstruate" while on the pill. The nurse practitioner said it was just annoying breakthrough bleeding and put me on a slightly higher dose pill.

Basically, I just want to know if anyone else has experienced this. I know most women conform to the dominant woman's cycle, but I've never heard this happening with someone on HBC. Am I just incredibly sensitive to other women's phermones?

could you move your placebo week to when your roommates are having their period? I've never heard of it overriding HBC, but that seems simpler than fighting it.
