Help me with this

Brittany
So I had sex and my partner came inside of me and I know it says to wait seven days after getting the IUD put in but I waited five days and I used two spermicide film squares and I let his cum empty out of me and I used a washcloth to wipe as much as I could get out. Also my period started two days after having the IUD 
How much of a chance do I have of getting pregnant now?
