Previfem Review

Do not take an additional pill to compensate for a missed one. If you encounter this situation regularly, think about the possibility of setting reminders or ask one of your family members to follow the schedule. Be sure to contact your doctor to adjust the schedule to compensate for a missed dose (in case you missed a significant number of days).
