"it works well as a birth control however i have been on different forms of ortho tri cycle for 10 years and the insurance company just recently switched me to this after i had my daughter. i have never had any side effects from any other pill but these make me nauseous and lightheaded about a half hour after i take them and it lasts all day. i&#039;ve tried taking them with food, water, at night. nothing helps. privifem and spritec were sooo much better."
