Hiya Blondie - I just thought i would reply to your thread as I am in the same position.

I have no idea what day i 'O'ed (if i did at all) but 2 nights ago I got really bad cramps, starting high in my tummy and actually having shooting pains going down to my groin....then a day before that I had a little bit of brown/red spotting only when I wiped....

I have taken 3 hpt and all BFN!!! I am getting so discouraged now...also am having headaches, nausea, gassy and bloating so I don't know what is going on!
