I'm almost positive I'm pregnant but still getting BFN

I am 6 days late today. I had VERY light cramps on and off from day 1 of missed period to day 4 of missed period. ( My periods are 3 days long) They were so light i barely notice the cramps. I had no bleeding not even spotting, and dry CM. My boobs feel heavy and hot and my nipples are sooo sore.

Still getting BFN though. The cramping during my period window is really throwing me off, why wouldn't i bleed? My periods are really regular but getting BFN is so annoying!

I wish either AF showed or i got a BFP, the suspense is killing me!

Anyone else have cramps during period window?
