7dpo, not saying I’m pregnant, I have questions

Hi so I am 7DPO and today I’ve been having waves of nausea but don’t need to puke, weird stomach pains since 2 days after ovulation, bloat bad after eating but I think I just have to poop, haven’t been able to poop that much but when I do it’s a bunch and my stomach still doesn’t go down enough, my feet has been hurting but I think it’s cus if my flats, left armpit sore but probably just a swollen lymph node, and when I leave my house my nose burns for a while.

I’ve thought I was pregnant in the past but that’s because every period I’ve had the PMS symptoms were so different from the last period symptoms, my ph balance would change and I’d get musty quicker. My period would also be 2-3 days late. The whole thing is confusing. I honestly don’t get my hopes up anymore and just wait to take a test and consider all symptoms as PMS but why is my body reacting differently every menstrual?

If anyone relates please comment. Thank you lovely people. Hope you’re having a great day!
