So, I've never had sex with my boyfriend but we went a little to far and he ended up cumming on me. Around my upper right hip, and like my lower left hip. I wiped it off right away and I'm like 99.9% sure he didn't cum on my vagina. So, why am I not getting my period? Today is day thirty and nothing...is there like any way the cum could have gotten on my vangina? I just started school not to long ago so I'm kinda stressed and I'm waking up a lot earlier and going to sleep earlier to and doing more in the day so I dont know if that would effect it at all...Please, Please, Please help!
