me and my girlfriend fooled around i got a wank and fingered her there may have been some pre cum on my finger and i masturbated that day.. she got bloated after and at the end of the month got her period as expected, she is only 15 but she got it around the time she expected anyway it was real heavy but the month before was real light so that kind of explains that but could she be pregnant from that even after getting the period she had breast growth recently too and also needs to pee alot but cant go and this could just be a kidney infection she will be getting that checked this weekend, but im worried sick thinking she could be pregnant were too young, but she did get her period when she expected it.. so im not sure, please help.. thanks!
