Retest?

Faith
My husband and I have only been TTC since December but thankfully my cycle is spot on to the day. This cycle I am 2 days late with slight cramping 2 days ago. Last night I took an EPT digital pregnancy test and it said not pregnant. I still have no AF symptoms or spotting. Any suggestions? Use another test? Or non digital better at finding the hormones because they can be faint lines? Thank you in advance everyone! This is the first time we have had some hope.
