Sex first week of birth control, AND on ovulation day.

Hello ladies! I recently had a miscarriage in July and began taking birth control up until I decided to discontinue taking it in October. I just recently started a new pill this month. My period ended on 1/10/17 and I took the first pill on the following Sunday 1/15/17. Well yesterday would have been my 6th pill, and also my ovulation day. My SO and I got a little carried away last night and he ended up finishing inside of me. Darn wine! 

My question is, what are the possibilities of me becoming pregnant now? I know they typically recommend using protection 7 days after the first pill. So since I was only on day 6 could I still fall pregnant? Thanks in advance!
