I'm not sure if I am, I may just be overreacting, but I want to ask others. My boyfriend and I had sex on August 27, The day after I finished my period and the week 3 days before I was supposed be at the optimal time for fertility. We used a condom, but it did have an air bubble in it. When he took it off, there was no visible hole,though. I've been paranoid since. My next period is still 9 days out. I've noticed an increase in vaginal secretion, a few lower abdominal cramps, a few headaches, and nearly constant nausea, though I haven't vomited at all. What are the chances I'm pregnant?
