Thoughts?

So this is about to be long. My period started on the 4th of this month and ended on the 8th. the last day was hardly anything, but i still counted it... only the first 2 days did i have to wear a tampon and the last few were so light i only had blood when i wiped. which isnt normal, even my last few days of my regular periods i at least have to wear a light tampon. So here's the question... is it possible to ovulate sooner than expected? i have 3 trackers and normally cramping and breast pain are my symptoms for ovulation but those symptoms normally come before my "expected fertile days/ovulation" since friday i have had extreme lower back pain and breast/nipple tenderness and cramping but as the days have gone by i have had noticed joint pains... certain times i am freezing and that makes the pains worse. now when i do get home im completely fine. I've also had some nausea and the last 2 days ive developed a little tickle in my throat. I absolutely do not feel sick! just achey certain times of the day and the tickle in my throat. also this morning i could smell my husband cooking in the kitchen, something i normally like but hated smelling it and then at work i walked by the breakroom and smelled something that made me gag. i have taken 1 test a few days ago that came up faint (yes it was blue dye... yes i know some hate it, but i also know some swear by it, so no negative comments about that please) and then 2 that were negative. very confused. my period isnt projected to start til the 3rd of october. so i know its super early. i m sorry for this being so long but im wondering if any other mamas experienced something like this! thanks in advance.
