I have been on Yaz for almost 2 months now but this month i missed the second pill in week one, then the first pill in week two, and now fourth pill in week three. I have two more days of "active" pills then start the "reminder" pills on the third day. I was also on antibiotics starting the end of week two thru half of week three... I know missing any pill will decrease the effectivness but my question is wether it will "significintly" reduce the effectivness since I didnt miss any in a row but throwing in the ordeal with the antibiotics...also just started getting some pretty bad cramps yesterday evening that lasted thru the night and still bothersome today, cramps are not usual for my body..any thoughts are helpful! Thank you...
