I had my Mirena removed on 6/16/16 because it was not in place... On 6/17 & 6/18 I had unprotected sex; bf pulled out kept wiping off the pre cum and pulled out when ejaculating... I was due and started my period on 6/19, but it is not a normal period... Should I have taken the Plan B pill anyway I know it says 72 hours but all websites say 5 days, even though I started my period?
