Does fennel tea affect the effectiveness of contraception?

Can fennel tea reduce the effectiveness of birth control pills? For 10 months I have been using Sylvie (first 30, then 20) and I do not complain about side effects apart from recurrent discomfort in the lower abdomen. Fennel helps me to deal with it, but on the Internet I have not found a clear answer as to whether its use can interfere with the effectiveness of pills. I would add that I take Sylvie 20 tablets every day at 9:30 with a slip to +/-20 minutes, and I drink dill tea late in the evening. Maybe I should give it up and look for some supplement or tablets that support the work of the intestines? Please help.
