Must i take statins if a healthy woman?

No: The drug companies are pushing it but if you don't have high cholesterol, high blood pressure, diabetes, history of heart attack or stroke, or significant family history of early heart disease, then there is little reason to be on a statin. If you eat far more veggies than meats and go out to eat rarely, that will also keep your cholesterol down. Discuss with your doctor why you need to be on it.

It Depends: Talk to your physician. Your level of cardiovascular risk (high, moderate, or low) is the first thing to consider. Ldl-c goals vary by risk (goal < 100 if high risk, otherwise < 130). If not at goal with diet, exercise and treatment of conditions affecting LDL levels, statins may be needed. If meds are started LDL particle number (ldl-p) should be checked on treatment to judge adequacy of therapy.
