Getting pregnant right after Mirena removal..

Michelle
Three weeks post mirena. I was supposed to start the mini pill immediately after removal but I wasn't consistent (as in same time everyday). I had some spotting on June 3 until June 6. (I spotted same time every month so I guess that was my period) Mirena was removed June 8. Unprotected sex June 7, 10, 11, 14, 15, and 17.  Is it a chance that I could get pregnant this soon?
