Pregnancy possible without intercourse ?

hello. i ejected right above my girl friends vagina, we were sitting under the shower. i ejected in water and probably on her pubic hair. im scared what if the water helped the sperm travel into her vagina (sperm can swim right!) it was her most fertile time. me and her are freaking out over the idea of her getting pregnant. this happened on the 28th of may, her period is due on the 11th or the 12th. the vagina has the capability to suck in water, im worried what if along with the water, the sperm entered her body, the girl is still a virgin, never had sex. she complained she had white kinda sticky particles on her pubic hair, could it be her semen or mine? help me, picturize the whole situation and let me know your honest opinion. i dont want to wait till her periods.
