Am I going crazy?!

Meg • TTC after losing our baby girl at 37 weeks 👼🏻
I am 9 DPO and starting at 7 DPO, I have been experiencing breast tenderness off and on (mostly on), nausea In the afternoons, headaches every day, and just last night woke up to pee FOUR times! I usually don't get up at all to pee. 
Also, I spotted on the day of ovulation and for the following 5 days. I never spot mid cycle... 
Isn't it way to early to be experiencing symptoms like this?! I haven't taken a test yet because I just feel like it's a waste and should just wait until at least Saturday (5 days before AF is due).
