I went to the clinic for a depo shot but they didn't test if i could be pregnant i got the shot for the first time in 1 year so ive been having pregnancy symptoms and negative pregnancy test i'm 5 days late with my period i have white discharge?

You may repeat the home pregnancy test in 4-5 days, unless you get a period by then. Or you could get a blood test for HCG to settle the issue now. For healthy diet: http://www.choosemyplate.gov/., exercise 30 minutes/day, drink enough water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs. Get HPV and Covid vaccines. Wish you good health!
