Efficacy of a new postpartum transition protocol for avoiding pregnancy

Area of Science:

• Reproductive Health
• Family Planning
• Postpartum Care

Background:

• The postpartum period presents significant family planning challenges, particularly for breastfeeding women.
• Breastfeeding can delay menstruation (lactational amenorrhea), yet ovulation may precede the first menstrual period.
• A protocol was developed to aid women in recognizing their return to fertility postpartum to prevent pregnancy.

Purpose of the Study:

• To evaluate the effectiveness of an online postpartum fertility awareness protocol for pregnancy prevention.
• To assess the unintentional pregnancy rate among postpartum women using a fertility monitoring system.

Main Methods:

• A prospective, 12-month longitudinal cohort study involving 198 postpartum women (aged 20-45).
• Participants received online or in-person instruction on a pregnancy avoidance protocol using a fertility monitor to detect urinary estrogen and luteinizing hormone changes.
• Pregnancy rates were calculated using Kaplan-Meier survival analysis over 12 months postpartum.

Main Results:

• The overall unintentional pregnancy rate was 8 per 100 women at 12 months postpartum.
• When used correctly, the protocol led to only 2 unintended pregnancies per 100 women at 12 months.

Conclusions:

• An online postpartum fertility awareness protocol can be an effective tool for pregnancy prevention.
• This method assists women in identifying their fertile window during the transition to regular menstrual cycles.
