Me and my partner are using fams in conjunction with condoms, but a couple of questions come up as far as when it is " safest" to have sex during her cycle whether it be before or after her "fertile period"(we give it 5 days before and after the day)?

If : 28 day cycle, ovulation would be day 14, most fertile time. If ovulating and a 21 day cycle, then ovulation is day 7. If cycle is 35 days, ovulation is day 21, and so on. As you can see this can vary, particularly if cycle length changes, month to month. Learning about basal body temperatures, and ovulation cervical mucus changes could be very useful in your planning.
