Does pulling out matter?!

So my husband and I have decided to not try for a baby until we move to our new house this time next year. We dont use condoms at all and Im not on birth control. When we have sex he just pulls out before he "gets it". The last time we did it, I was on my ovulation window on my peek day! Im supposed to start my period in 3 days. How big of a chance do you think I have being pregnant?! In almost 4 years we have never had pull out sex when Im ovulating bc we were afraid I could get pregnant. This time we couldnt help ourselves!

Any ideas? lol If we are we will tak it as God's plan but Im scared! lol We have a lot of financial things in play for 2018 and we really cant afford a baby right now. God, that makes me sound horrible! :(
