help yall

okay so in february i slept with my boyfriend without protection, it wasn’t exactly proper sex but he still came, and he pulled out and after about 5 seconds he came into his hand sort of thing, and i completely freaked out and started crying, and i took the morning after pill the next morning. Two weeks later i got my period, and i have had two more normal heavy periods after that, but i have been so paranoid and upset and freaking out constantly since it happened and i’ve taken two tests, about a month apart, and both came out negative. It’s like in my brain i know i’m not pregnant, but i’m still so upset about it and need reassuring. please help!!
