I am about to start a new BC but I started my period today. I am not sure what my doctor is putting me on. I am suppose to go pick up samples tonight. I am getting on BC because I am getting married in June and we don't want any more children right away. My question is when do I start the pills? Today since I started my period or the last day of my period? I was on BC 6 years ago but I can't remember anything but throwing up from them. Are there any other side effects? Weight gain? Moodiness? Tired?
