My boyfriend and I had unprotected sex for a few mins and I'm afraid that his precum will leak into my vagina and get me pregnant. He did not cum into me and ejaculated 2 days ago. I'm aware that precum may get me pregnant if it contains leftover sperms from the last ejaculation but I'm still scared. He did urinate since his last ejaculation 2 days ago but we're still scared that there's a chance of him getting me pregnant. After he pulled out I touched his head and it was dry. But I'm really unsure whether I could still get pregnant from this incident. Do you think there's a big chance/ percentage of me getting pregnant?
