Linger, I'm not trying to debate you on whether or not BC is going work or tell her DON'T DO IT! IT RUINS EVERYTHING. Speaking from my own experience, as many other posters are, I'm saying since it is 13 months from now, it wouldn't be MY first choice. I was on the pill for five years and got my period plenty of times I didn't want it. It's not 100% but I'm just playing the other side of the field. I never said she should change her wedding day, or that it wasn't at all important to have sex on your wedding night but mother nature is going to happen regardless.
