"my boyfriend and i had unprotected sex and he had cum earlier in that day but had not peed yet so there could&#039;ve been cum still in the precum. i was on a day when i could have been ovulating, i had it in 3 hours. i was thinking that i was really pregnant this time. i was getting cramps on one side and back aches, with w little bit of spotting and i thought it was implantation. being only 14 i was super worried then today my predicted day of period. i got it!! i&#039;ve never been happier in my life"
