I Have Currently Been On Birth Control (The Pill) For Almost A Year & A Half & Today Im Starting My Prenatal Pills/Vitamens But Im Not Pregnant. My Auntie Took Me To Buy Some Prenatal Pills So I Can Gain Weight , Make My Hair Grow Longer (Already Long) , & Help My Face Clearer & Nails Grow Long , Pretty & Strong. That's The Only Reason I'm Taking Them Because I'm 17 & I'm Only 110 Lbs . I Haven't Took Them Yet Because I Need Advice On If It's Good Or Not Good To Take The Pills While On Birth Control . Any ADVICE ??
