Similar to any of you?

Can I get some insight here...so I told you about the bleeding doing a disappearing act on me...still happening even now. Anyway I took another cheapie preggo test yesterday still negative. I woke up today to my daughter wanting to be fed and some serious cramping while feeding her I had this really strong cramp. What is going on? I'm probably really naive to think any type of pregnancy could happen this late in my cycle or lack thereof right?
