Okay, so a couple of things. First, women do not ovulate when pregnant. That would be a one in 10 million chance. Some women DO spot during early pregnancy though. You risked pregnancy with unprotected sex even if he didn't ejaculate. If you took the pregnancy test 2.5 weeks after you had sex or when your period was due, then that is a good sign you are not pregnant. Otherwise, make sure you didn't take it too early. Doesn't sound like you are pregnant. good luck
