Quickie. Need answers fast

So me and my BF were on the couch and he asked to slide in and I let him . He stuck it in for a couple minutes and took it out . This went on for like 20 minutes . The last time he stook it in he started going faster and eventually came . He pulled out before he came . I however did not orgasm . Is there a chance I could be pregnant . Is there a chance that precum can get me pregnant on this situation
