Hi Lizziep!
I have been on Evorel Conti for 2 months, and like you have had a period every two weeks, after the first month. But I found that when mine came it was very weak and pale, but made me feel well again, bizarre! I had cramps, and everything, after nearly five years! Lasted about 5 days, but was never really "red". Consultant said it was expected, but should stop after 3 - 6 months.
