Help!!

li
So my last "period" was July 9th, it came 6 days early and was light compared to my normal period. I've been having to pee alot and over been having diarrhea (sorry for the tmi) almost constant since then. I've been having this pinching cramping feeling since then. Glow says there is 10 more days till my next period. Also with my last one there was a lot more brown discharge than usual. I've also been so laazzzyy like I never want to get out of bed I'm just so tired and just don't want to move. Also been very moody it's like everything my fiance does just irritates me. I haven't taken a test at all, the last time I did was the 10th of July and it was a bfn. I've also been eating a lot more too. Is it possible or am I just crazy??
