I am currently taking Levonor -Eth estrad. The pills that where in the first 3 rows where white. The last row is a peach color which is when I am suppose to get my period. I didn't get it which is normal my first month. I had unprotected sex on the second day of my peach color pills. Am I still protected like I was the first 3 rows or am I not suppose to have unprotected sex in this week?
