Worried

I’ve been worried lately that my girlfriend could possibly be pregnant , I’ve been doing research and asking live chats and nobody can really give me a good solid answer so here is my situation, I went over to my girlfriends house and we weren’t planning to have sex for two reasons because she was ovulating and I didn’t have a condom so we did not have sex but I still ejaculated . Most of it got on my stomach and some of it on her boob but I’m 99% percent sure it got no where near her vagina . I’m just afraid because I’ve been reading that if my penis came in contact with her vagina she could get pregnant because of pre-cum but before that she had giving me a “ blow job “ and lately I’ve been just overthinking everything lately. Can someone just relief me of this anxiety thank you it would be appreciated sorry if my grammar isn’t the greatest
