Assuming you aren't ready to have kids, you're most likely using some sort of birth control. But since condoms are only 85 percent effective, and IUCs and the pill are 99 percent effective, there is that small chance you could still get pregnant. So with that said, waiting for your period to come can be a nerve-wracking event. And even though getting your period and suffering through everything that comes with it isn't fun, when I'm sexually active, I'm almost elated when it comes! Are you ladies with me in this one? Do you get that relieved, excited feeling when your monthly friend comes even though you're using protection?
