ok I knew this would happen... I got the 3 month shot.. I got my first shot in late june not sure when I forgot. And I was scheduled to get my next shot on sept 16th and I couldn't make it cuz I had to get my wisdom teeth out. So I had to reschedule to the 26th and since the 16th me and my b/f had sex. He pulled out before the big bomb but what about the pre-stuff !!!!!!!No condom... :( should I be worried if im pregnant??????
