Guinea Pig? guess I am the only one on Natazia and have been for almost two months now. I have not had a menstrual cycle since starting these pills... I even took a pregnancy test and it was negative, but I am still a little leary on the results because I am not sure if birth control interferes with results? The box for Natazia says if I have no cycle for two months, I MAY be pregnant. So, is it safe for me to continue taking the pills if I am?
