10dpo and everything feels like a symptom

Like the title says I’m 10dpo and I just want to test and know for sure already (I’ve been testing the past 2 days but been negative) and man it feels like everything could be a symptom. Is it cramps or gas? Is my backache something? Are my sore boobs a symptom or just a side effect of not wearing a bra the past 2 months? How is everyone else doing? How are you managing? Also if your testing when do you do it? I know they say use your fmu but I get up 2-3 times a night to pee so I don’t know if that would be good. Thoughts?
