Could I be pregnant or am I just overreacting?

So my fiancé and I had sex 3 days before my predicted ovulation, and he finished inside me with no protection and I’m not on the pill either. I’m now 5 days late and not having any of my usual “my period is starting soon” signs like feeling bloated and getting minor cramps or my usual cravings. I just took a test because we’re both a little freaked out and it was negative, it’s also just from the dollar store if that makes a difference.

I don’t want to be freaking out but I feel like no matter how many tests I take that come back negative I’m not gonna be at ease until my period comes.
