Is it possible that vitamin C taken only with food reduces the effectiveness of hormonal contraception?

Good morning I have two questions The doctor changed my pills from Orlifique to Vibin, she said that after the last active tablet of Orlifique you should immediately start taking Vibin Tj skip the placebo from Orlifique and do not take a break between pills Will this provide a full contraceptive effect ? Will protection against pregnancy be maintained? The second question concerns vitamin C, whether without supplementation of this vitamin, assuming an ordinary diet, there are no fears that its excess could reduce the contraceptive effectiveness of pills? I will be grateful for your help Regards
