What are some side effects of birth control pills? Would it be worth it to take them just to decrease my periods? What are some common pill options?

Lots of options . Many people take birth control for cycle control. This is a common. Loestrin 24 or gianvi (drospirenone and ethinyl estradiol) are popular brands. Seasonique decreases periods to 4x/yr. Mirena iud stops them completely in many patients. Common side effects are nausea and bleeding at the wrong time. Remember birth control decreases risk of ovarian, colon and uterine cancer.
