... the problem, but I feel like I'm pregnant. (I know it sounds crazy).. I'm sexually active with my partner and we use protection ALWAYS. I'm anxious to start my period and I was wondering what color pill am I subjected to start my cycle? I'm currently on my last light blue pill. I've also change my whole cycle patterned causing me to add an extra 2 weeks to the wait on my cycle. Is there a possibility that I'm pregnant or it's just the side effects?
