I haven't had my period for 3 months. Then I got prescribed medroxyprogesterone so I could restart my period. After taking all the dosage it started 3 days after I stopped taking it. Then I started Tri-lo Sprintec. My period has lasted 11 days and still going. What's wrong with me and what could be the risks?

Time to see your doctor again. Your doctor knows your medical history, and he/she is the one that prescribed these meds. You won't get a diagnosis online, it's impossible to do, so you'll have to see your doctor if you want to figure this out.

Good luck.
