I was on lutera birth control pills for two months, and those months my period was normal. I stopped taking them for a month, then started again. This month my period came on time, on the second day of the sugar pills, but it was much lighter and much shorter than usual. I had cramps and other PMS symptoms. Is this my period? I don't want to be pregnant, so I'm hoping it is. I don't "feel" pregnant and I've had no pregnancy symptoms, but the light period is worrying me. Is this normal on lutera? Even though I've taken it previously with out this effect?
