Late period??

Rebekah

So, my cycles are usually 25 days. Today I passed 28. We’ve been ttc for 5 months. I took a test the day my period was *supposed* to start and I didn’t really see a positive. I saw maybe the faintest evap line. That was about 12 DPO. I’m now 14 DPO, should I test again or just wait for AF?
