Pregnant chances?

Me and my boyfriend had unprotected sex yesterday for the first time. We normally always use condoms but I wasn't thinking clearly and begged him to go in just a couple of times. He never finished and when he came out I gave him a handjob but that took about five minuets so he wasn't near finishing. He had not ejagulated that day so there isn't a chance of any sperm being left in it.
​I'm on the 12th day of my cycle and I have a pretty regular cycle (26 days/27days) I'm really scared but he isn't. We both decided to wait until we get married to have sex again because the anxiety just isn't worth it.
​What are my chances of being pregnant from this?
