Should I test tomorrow?

My husband and I are trying to conceive baby #1! I am supposed to start my period tomorrow Friday 1/22, but took a pregnancy test on Monday 1/18 because I was too excited to wait (and glow said I could take it Tuesday). The test was negative, and I'm wondering if I should retest tomorrow or just wait and see how things go? I don't want to get my hopes up again and waste another pregnancy test.
