In studies conducted by the World Health Organization and researchers to determine if breastfeeding can effectively prevent pregnancy, results have shown that in 98 percent of the times, breastfeeding was a barrier to conception if three criteria were met
- You must be fully or nearly fully breastfeeding. This means you should be breastfeeding at night and have regular and small intervals between feeding times.
- You have not resumed your menstrual periods. Any kind of vaginal bleeding after the 56th postpartum day is a sign that fertility has returned.
- Your baby is younger than six months.
If you are engaging in sexual intercourse, the safest bet is to wear condom for peace of mind.
