My girlfriend had been on
birth control for about two years. She always had her period on a saturday. Always. She had to stop taking the pills for a month (her prescription was messed up), but once she got her pills back, she didn't wait for her period to start before starting the pills. So my question is, would it be normal for her period to start on a saturday still? Because the period after she started the pills again started on a saturday and lasted for nine days.
