How Long Does Femulen Take To Be Completely Out Of The System?

I took Femulen mini pill for about 8 years. Stopped taking it 9 months ago and trying to get pregnant. Is there a certain amount of time I should expect for it to get out of my system. I understand it is not a relatively long time to have been trying to conceive but I always have the feeling I was on the pill for too long. Thanks
