no period but not pregnant

okay you guys i wanted to wait a whole before I wrote on my topic to make sure I'm not going crazy...I just gotta know what's going on with my body, so if you've bad simulates or anything let me know feel free to chim in will you...okay so my cycle was suppose to be here by August 24th of last month, I didn't have it so I waited the 2 weeks and tested by Sept 4th, I gotten a negative, so I said I'll wait additional 6 more days before I test again, and tested on Sept 10th and still got a negative with the digital reading this time...so at this point I'm thinking my cycle is gonna come or should be here cause I keep having the headaches that I normally get right before af, but still nothing, everyone keeps telling me it's because of stress that's holding it back and I'm starting to think that, so okay come this morning the 12th of Sept I jumped outta my sleep about 330 in the morning thinking I had peed myself cause that's what it felt like or I thought I'd started my period, it was a wet spot tho but didn't smell like pee, so when I went to the bathroom to actually use it, there was nothing there, so I started researching and I'm thinking maybe a wet dream...lol what do yall think? and like I said no I don't think I'm, pregannt, but should I retake a test, or is it just my hormones out of wack, most times I have a very irregular period if I'm not telling something to fix it. but never had the wet the bed problem, I also read uh it could be a form of your period just a clear version of it, is this true? if anyone may know other there saying your PREGNANT feel free to respond, not everything point to pregnancy ppl, I just wanna know if anyone had anything simular problem? and what can you do to fix it? I do have a doc appointment on the 22nd and I'm jotting down everything going currently on...but feel free to comment please...just looking for answers
