Several times in the last year, I have had a cancellation of a scheduled appointment due to a "pink vacation".  The PO has always been most helpful in rescheduling another girl for the same time.  As you know, women on the pill do not have menstruation periods, so I was surprised to discover that they were not all on the pill.  I am assuming the ones that do BBFS must be on the pill, but I do not visit them.  So I asked Tera who always puts on a condemn for me if she has a "pink vacation" and she replied yes.  I asked if she was concerned about getting pregrenent, and she replied that the condoms were safe.  She alternates months, taking the pill for a while and then going natural without the pill for a while.  It was better for her health.
