getting nutted in while ovulating

So my boyfriend has been nutting in me for the past 5 days, come to realize today is my first day of ovulation which he nutted in me today and yesterday. What are the chances of getting pregnant? Not that I don't want a baby because I do!!! I'm just wondering 
Update: were not TRYING to conceive but if it happened we wouldn't be upset bc we both love kids, and want our own but we're 19 & 20, live together, school & work full time.
