A member asked:

On bc pill. had sex 3 wks ago. keep track of period (same as usual) usually last 6-7 days but only 4 days this time. could it be implantation?

A doctor has provided 1 answer

Unlikely: Women on birth control pills are unlikely to conceive, and without conception, there is no embryo for implantation. If worried, one can check a home urine pregnancy test. They give a reliable result about 3 weeks after sex or 1 week after having a "weird" withdrawal period, or after missing a withdrawal period.
