Anyone else?

I'm five days late for my period. I've had little cramps here and there. I've never missed my period or been late for my period because they are ALWAYS regular. I took a pregnancy test when I was a day late and it was negative. I figure it was negative because I know the more you pee it lowers your levels of HGC and I used the bathroom like 4 before just checking to see if my period had came. I haven't took another yet because I'm just gonna wait till the end of the week. But every since Friday, it's not even occurred every day and sometimes it's only when I go to wipe, I had a very very light brown color mixed with my CM. Do y'all think I could be pregnant? It's this normal in early pregnancy if so?
