Really Panicking!!

So I've never posted on here before but I'm really panicking. So my boyfriend and I did it the other day and I didn't know until later that it was the second to last day of my green week or "fertile" week. We used the pull-out method which I know only works if you use it correctly, and had sex twice and he is completely positive he moved before he came. But what worries me is that he didn't go to the bathroom between times and there could be a chance that there was sperm in the pre-cum? So I hesitated a bit and took plan b within the 72 hour window but closer to like 66 or so hours. I've taken it before and felt side effects right away and now I feel nothing. I'm really freaking out and don't know what to do. If anyone has any suggestions or anything please help 😥
