When should I test?

One app says I'm 4 days late and this glow app says I'm supposed to start AF tomorrow. Should I wait and see if AF comes or go ahead and test?? Just really don't wanna test too early, but haven't really had any AF symptoms. The only pregnancy symptom I really have is sore breasts which ive had for a week now&I've been super tired but I think that might be from my new antibiotics I've been taking.. So test now or wait??
