Lost my virginity!

Hi guys so I recently lost my virginity to my boyfriend and it was nice and comforting knowing I lost it to someone I love but I'm freaking out because i have this app called pink pad and it lets you know when your ovulating, fertile and etc. similar to this app. Well when we had sex I didn't know I was ovulating, until after we finished and I checked my app. And I'm freaking out because we didn't use a condom and I am not on birth control! ( I'm 16 and I come from a really strict family) what should I do??? I haven't gotten my period yet and my app says I shouldn't get it for another 8 days. I'm freaking out please help!!!
