I'm 17, i had sex three months ago with my boyfriend at the time. Im not on birth control and the last time we had sex he didnt use a condom, i know very stupid of me. I've two periods after thar, but this third month hasn't came yet. I have all the signs like im going to start, bloating, lower back cramps, break outs, mood swings, and all that but it hasnt came yet. My periods are usually never off track, unless i have an energy drink and this month i dranks a monster so i dont know if that could be the cause of it or what. Also he is a really big pot head and he says it lowers guys sperm count but i dont know. Im freaking out, first and last time i have un protected sex. Feedback please! And thank u
