Pregnant after mirena removal

Kristi

I switched from mirena to pills on Dec 22nd and had unprotected sex the day before mirena came out Dec 21st and the day after mirena came out Dec 23rd my so didn't pull out either time so now I'm wondering how likely is it that I'm pregnant. ... ..do you ovulate right away after mirena is taken out ? I started bleeding very heavily Dec 24th thru the 27th (not a normal period)

Just looked at my calendar and it was removed during my fertile period
