Multi-vitamins and birth control..

[foureyedgirl.livejournal.com]

I have decided to start taking vitamins in hopes to help my health and chronic pain, but I want to make sure that the vitamins won't interfere with my birth control pills. I'm taking Microgestin Fe 1/20 and I'm not currently sexually active (I know I am probably weird for even asking this question when I am not even having sex..).

I have googled and found mostly nothing suggesting vitamins being a problem except for this:
Tell your doctor or pharmacist if you have any medical conditions, especially if any of the following apply to you:
if you are taking any prescription or nonprescription medicine, herbal preparation, or dietary supplement

What do you all think? Should I just go ahead and call PP to make sure?
If it helps, these are the vitamins:
