Fish Oil and Vitamin D supplements, Ok to use?

I've been using the birth control pills Aubra for over a year with no problems. I've recently (≈ 2 and a half weeks) started taking vitamin D and Omega 3 supplements. I was reading and found out that Flaxseed (in Omega 3 with fish-oil) can decrease the effectiveness of birth control pills. I am sexually active and use the pill as the main pregnancy preventing method alongside pulling out.

I was wondering if anyone is more informed on this subject, if it is ok for me to continue taking these supplements?

Advice is greatly appreciated!
