Levonorgestrel
"Hey everyone. Taking this pill saved my life. Im 18 and just started college, i had sex with condoms but it was my first time and I heard a pop (=didn't know what it was). I felt like being pregnant would be so unfair, especially since we did use contraceptives. My boobs hurt a lot thoughout the process, i had severe back pain, i was tired, really moody, and freaking out for 3 weeks because i thought i was pregnant. I got my period 2 days early, thought it was implantation bleeding, but took 4 tests and they all said negative. I'm telling you this messes up your hormones big time. your period is not gonna be the same most probably, and that's normal. Just relax guys, this works. stress makes it worse!!!!! and it could push back your period!!"
