Umm.. what?!

Okay so I have quiet a few symptoms and I don’t know what they could be.. I’ve been having UTI like symptoms but I do not have a UTI.. I get a weird crampy feeling in my lower abdomen and some times it kinda feels like a tingly sensation or like a tickle.. it comes and goes sometimes. I also recently have been getting headaches here and there... and I never get headaches.. I haven’t had a headache or migraine in 2 years till just recently.. I pee A LOT more than usual. Doctor did UTI test came back negative.. so I’m at a loss.. I’ve been having a lot of different cravings.. sometimes I’m stuck on 1 specific thing until I get that.. I’m moody.. my period isn’t due for another 9 days I believe.. what do you think? I’ve also just started to get some lower back cramps which isnt my normal pms symptoms.. normally its sometimes my boobs hurt or it just comes. I dont really get pms stuff and I have notice sometimes I get nauseous around a specific time... mornings and or evenings.
