Worried, can’t stop shaking.

Hi ladies. Please no rude comments, I’m already dealing with enough and have no one to turn to. It’s okay to educate me, but please be nice. So I had sex a few days ago, we always use a condom, but this time he put his penis on my vagina, like on my hole without a condom. So I don’t know if he had precum when he put it there. He didn’t go in until later when he put a condom on. Then the condom started coming off, but he’s saying he caught it before it could slip and he then quickly pulled out and completely took it off. Neither of us came/finished, like after he took it off we didn’t continue having sex. On that day, eve showed that I would be ovulating in 6-7 days. I took a Plan B since I am not on birth control, however I’m scared it won’t work for me because apparently Plan B only works for people 165 pounds or lighter, I’m 180. I took the Plan B 25-26 hours after sex, which was 2 days ago.

Even though I wasn’t ovulating, according to eve, could I get pregnant from precum? I’m so worried. I’m always so careful... I read that if he pees before then it’s fine and I’m sure he did, because there’s no way he went all day without peeing. I also peed right after, but I’m worried that it traveled somehow inside me or that the Plan B won’t work.
