How many days past your missed period did you get a positive?

Hi, Im a type 1 diabetic, 20 years old, and my period is usually always on time or maybe a day late. Well now I’m 5 days late, and I’m having pregnancy symptoms ( sore breasts, mild cramping, fatigue) but the tests I’ve taken so far are negative. How late did you get your positive result? Could I still be pregnant…?

I haven't been pregnant yet, but I did read the back of those pregnancy tests, and the ones you can buy at the store says 5 days before the expected period. Have you thought about making a doctor's appt for a test?
