I had protected sex last night. However, the condom broke, come to find out this morning that last night was my last day of ovulation, August 5th (my most likely to conceive day). He had not came in my and as soon as I heard the pop he pulled out. We went to a local drugstore and bought plan B. However, Im just now hearing that plan b does not work if you are ovulating or already have. Im freaking out, I'm supposed to be leaving for college in 3 days. How big of a risk do I have/How soon can I take a test and get an accurate result? My period is due August 17th. Please help, I'm only 18.
