What would you do? Thoughts?

TTC for 8 months now. Took a test on Thursday, AF was due Friday. It was negative. I still don't have my period and it's Sunday night. I'm hesitant to take another test because well... Negatives are depressing. I do feel fatigued and my breasts are tender... I just feel like I should wait a few more days, trying not to get my hopes too high.
