Pregnancy help!

Patient: Well my girlfriend and i were playing around. we didn’t have intercourse and she still is a virgin. we both think that my pre-cum maybe went into her vigina. but we’re not sureif it did or not. the day after that happened she got her period, that lasted about 6 days. after her period about two days later(a week and a day from we played with eachother) we got her pregnancy tests. she passed one of them. she accidently held it for her whole time peeing instead of 5 seconds. about 2 hours later she tries it again but could only pee for about 3 seconds. we don’t know what’s happening we need help.
