To test or wait?

Hi everyone! I've been TTC for over a year and a half already and haven't had any luck. AF was suppose to arrive on 4/16 and nothing yet, I marked it on Glow and it moved my expected day for tomorrow. I always use the ovia app for my period expecting day and it's always been accurate where it should've started yesterday. I've been having a bit of discharge with my panties being wet a lot and feeling dizzy, and cramps but they're not bad.. should I wait until tomorrow or test already?
