I had the Mirena IUD removed on Dec 28th, light bleeding for 5 days.  Had unprotected sex on Jan 10th, and started tri-cycl pill on the Jan 12.  Finished the pack and this is the 2nd day of the nonactive pills.  Is it possible to be pregnant.  Prior to the Mirena, I had the copper t for 10 years.
Hi there, Welcome to Chat Doctor, Since you had not taken any contraception after removal of the IRENA there is a possibility that you could be pregnant. It would have been more prudent on your part to take an emergency contraception before starting the new pack of Tricyclic pills. Or you could have waited for your next period before starting the pack. You should do a home pregnancy test once you finish your non-active pills. And start a new pack only after consulting a family physician or a gynecologist. Hope this helps. Regards.
