Whats going on??

As you can see from my tracker... I am on day 41 since my last period. FORTY ONE!
And I've taken three pregnancy tests, all negative. I did have spotting one day and I feel crampy but nothings coming, Im not having any more spotting and I dont really FEEL pregnant but obviously I cant help but wonder...

anyways, Im a bit frustrated and annoyed. I wish my period would come or that I would have a positive test, either way, I'd be happy just to have the relief of knowing for sure.
Anyone have any input?
