"this product works wonders. had unprotected sex after i had missed a few of my birth control pills. my period arrived at its usual time of the month, and it was not a heavier or lighter flow than usual...just normal. i did experience some bad pains and nausea in my stomach for about 6 hours after taking the pill. i also threw up two days later out of no where. other than that, it did what it&#039;s supposed to do."
