Possibly Pregnant

Hey ladies!
So I have a four month old, she is nearly five. And I had a period four weeks after having her via emergency c-section. I skipped this month and tested hpt the ninth of this month. I still haven't seen Aunt Flo. So I was wondering if any one has something profound to say? I am not ready for a second child and I was using bc methods. So to say the least I'm extremely nervous about the possibility.
