I have the std called trich for short i been on the medicine for almost a week me and my partner had unprotected sex while on treatment i'm scared?

Both of you need to be treated at the same time. The two of you should see a doctor together. You may wish to get checked for other STDs as well. Have a healthy diet, exercise 30 minutes/day, drink plenty of water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs.
