"I&#039;ve been taking Sprintec for 10 months and had no problems besides feeling a little nauseated at times and slight headaches. No major problems at all. I was prescribed this birth control due to heavy irregular periods. Since taking Sprintec I&#039;ve had regular periods lasts up to (3-4) days, sex has increased, feel more motivated and active. I would highly recommend this birth control because it works."
