No sperm leakage ????

K me n my bf are desperately trying to conceive !!! According to this app , I'm ovulating with 28% percent chance of getting pregnant. 🤔🤔🤔 anyway last night we had sex and for some reason it didn't leak out after he came . And usually it's all over the place running down my legs lol . This is the first time it's EVER happened. I've done some research and most ppl are saying that it will come out during the night or next day .... Still hasn't happened . Could I b pregnant??? Please say yes 😩😩😩
