9dpo HELP!

Ladies who knew this early please answer!!
I know it's early, trust me. But I just feel so off. I. am. exhausted. Currently sitting in class trying not to fall asleep tired
(Got 8 hours of sleep last night).
I am miserable. No clue why because it's a nice day outside, class is super easy today, and it's Friday but I am just 😑😡✋🏼.
My sex drive is ZERO.
I feel like crap. I eat the same thing for lunch every day and today it made me want to vomit.
Have not been able to poop in a week(completely odd for me), and my poor hubby... gas so bad that he leaves the room😂
Not currently sick. Haven't been sick. Still 6 days from period and I never PMS this early. Eating healthy. Working out daily. Haven't changed anything.
Did anyone who tracked their cycles and paid close attention to their symptoms before they found out feel this way? Tested this morning, thought I saw the faintest of lines, squinted at it, then threw it away because I always say if you have to squint you're looking too hard 😂
