Chances of pregnancy after progesterone was stopped?

Dear Ask The Doctor: Was on progesteon, stopped to have my period no bleeding, had unpotected sex for 3 days and then took morning after pill before 72 hours were up, could i be pregnant?

Dear Andra: Though the chances for pregnancy are minimal, I would advise taking a urinary pregnancy test after 2-3 weeks of the act. Blood-work to detect pregnancy can also be done as they detect pregnancy much earlier than a urine test. Hope the information helps, take care.
