... (who's been on the pill much longer then me). My sister and I both take them because while on our period we feel extremely sick. I'm on my period, on day four of the brown pills and I'm in a lot of pain. Will anything happen if I start a new pack today instead of waiting to finish the brown pills in the previous pack? (I'm on day four of my period and I just can't handle the unbearable pain anymore.) Thank you
