Oops! Is it possible!?

So I recently stepped out on my marriage. My husband hasn’t been giving me much attention and I was so craving some. Since November of 2019, we’ve only had sex 3x. One of which he couldn’t even stay hard and said “I’m just too tired”. I know he’s loyal. Here is the issue. He had a vasectomy in 2016. I’ve had no form of BC since 2017. The guy I slept with pulled out. But I’m worried. Should I be concerned or worried I could potentially get pregnant? No, the other guy didn’t wear protection. Let me also add, this is the first time in over 10 years I’ve ever done something like this.

I came clean to my husband. I hurt him but we are working through it. I’m not pregnant and we both got tested. Both are in the clear. I do feel bad that I stepped out. I feel horrible and haven’t been able to sleep properly since. I’ve also cut all contact with said guy. To this that didn’t judge, thank you. To those that did, wow. I know what I did was wrong but you shouldn’t judge someone so harshly.
