Only BFN's and not Af... who else is in this boat?

I've been testing like crazy (such a bad idea I know). I'm 3 days late and I dont know what to think. I already have a baby boy 18th moths, but I don't remember when I got my + with him.... I just want to know if I'm pregnant or not, so I can move foward. Because not knowing it's so hard.
