i just finished my period and a day later.. i foolishly had unprotected sex..
i had no intention of having unprotected sex.. and it was only for a few minutes....

..... he pulled out and insisted he hadnt ejaculated until after he had pulled out... but i knw that's not always the case..
im freaking out a bit so ive been trying to work out my cycle and see if there's any chance i could be in trouble... but all websites are saying i should wait until i miss my next period to take a test... which is now in 3 weeks... i dont know how mental im gonna go not knowing if im in trouble or not
what makes it worse is that it was a rebound from my bf that left me and moved out a week ago..

... im only 18 and ive had scares before.. but i'd just really appreciate some advice or words of experience because i really dont feel like i can talk to anyone about this.
thanks
