My husband and I are newly weds, and very young, (I'm 19 and he's 22) neither of us are ready for kids because he is a marine and wants to finish his contract before we start havin kids, but 5 days ago (1 day after my period) we had unprotected sex and he tried to pull out but wasn't fast enough and "finished" as he was pulling out. The next morning I took 'plan b' and felt a little sick to my stomach but didn't throw up, for the next 2 days I felt sick, then it went away. On the 3rd day I started having slight discharge and very light and sporadic cramping, but no other unusual symptoms. Am I pregnant? Or did Plan B work?
