Ah, yes. I had forgotten to mention that little trick in my earlier comments about using the pill to postpone a period. When I start a patient on birth control pills, I almost always recommend that she start the pills on a Sunday. That way she will take her last hormone pill three weeks later on a Saturday. She usually doesn’t start her period the first day she goes without a hormone pill (Sunday) but the second day without a hormone pill (Monday). Her period will end Thursday or maybe Friday. The same thing will happen every four weeks, and, as I tell her, she will have all her periods beginning on Mondays and ending on Thursdays or Fridays. That way she will have all her weekends free to party with her boyfriend or husband.
