Help!!?

So me and my boyfriend have been together for a year now, and in our 1 year anniversary we decided to be a little intimate. We never had sex I’m still a virgin, but he rubbed his penis onto my vagina (obviously with no pants or under wear on) and he checked and felt and said there was no precum so I believed him, and I even felt for myself. After he finished rubbing his penis on me he fingered me. And the day we did that I was 4 days off my fertile window so I felt as if I was ok. But then today (1 day after our 1 year) we decided to be frisky again. So he suggested he rubbed his penis on my vagina again and I was like okay but let me check and see if there’s precum so this time I took my phone flash light and shined it on his penis and we saw precum but it was a little bit like not a lot just a little droplets. And then we didn’t obviously rub his penis onto me and we both washed our hands. But now after seeing that and actually shining a light onto his penis I’m afraid that we could’ve missed anything on the first time we did it and now I’m a little concerned I could be pregnant. Because he fingered me after he rubbed his penis on me on our 1 year. Am I overreacting?
