Hello, I would be happy to help you with your question.
Usually at the the point that you have missed a period, the pregnancy
test will turn positive. So, I do not think that you are pregnant. Women can have a small amount of bleeding mid-cycle when they ovulate, so my best guess is that you had a delay in when you ovulated, which when it occurred you experienced normal bleeding and cramping, and your period should occur within two weeks. If it does not occur within two weeks, then repeat the pregnancy test.
I hope that this helps and good luck!
