pregnant? not pregnant? so confused

I am on cd 35. My cycle has never been this long before. I have had cramps for 5 days now, and many pregnancy symptoms. I think I ovulated a few days later than normal so I might only be 12-14 dpi now. But today I'm having some brown discharge, and still light cramps. Is there still a chance of pregnancy, or does cramps with spotting mean a bad sign? Yesterday my cervix was very high. I've never had cramps for more than 48 hours before getting my period. Anyone else experienced these things? What does it mean? I took 2 hpt and both were negative,  but that was a few days ago. But I read that cramps with spotting means no preg. Anyway, let me know what you think, please? Thanks!
