Im 16 and i was wondering if its safe for me to take fenugreek while also taking sertraline (zoloft) i want to increase breast size a little bit and help my digestion?

Fenugreek wii not do either. You should talk to your doctor who prescribed Zoloft and clear any medication, herbal or supplements with her/him. 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!
