Is there any other way to regulate my period without taking birth control? age 18 birth control pill used: sprintec

If : If you mean anything other than birth control pills, then yes there are other options. The NuvaRing is a good birth control method that can help regulate your periods. The ring is inserted at the start of you cycle, it stays in for three weeks, then is out for the last week. If you meant a natural method, then unfortunately there is nothing you can do other than maintain a healthy weight. Best of luck.
