Pregnancy During Withdrawal Bleeding: Is It Possible?

Withdrawal bleeding (the "period" during placebo pill week) typically indicates no pregnancy, but pregnancy can still occur during this time.

How It Happens

Withdrawal bleeding results from hormone level drops when active pills are paused. However, if ovulation occurs (due to missed pills, interactions, or individual variation) and unprotected sex happens, sperm can fertilize an egg.

Risk Factors

• Irregular pill use or missed doses
• Short menstrual cycles
• Early ovulation
• Medications reducing contraceptive effectiveness

Key Takeaway

The chance is generally low but not zero. To prevent pregnancy, use contraception consistently regardless of bleeding pattern. If concerned, take a pregnancy test and consult your provider.
