TTC and period is late

Annie
My period is 5 days late according to <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a>...obviously an app doesn't really know my body but this currently. Is the longest time between period for at least five months and my husband and I have been TTC for those five months. Should I take a test now or wait a few more days?
