Will 2000mg of vitamin C reduce the effectiveness of contraception?

Vitamin C used at a dose above 1000 mg can alter the absorption of ethinyl estradiol and make the cycle irregular, so the possibility of getting pregnant increases; also, abrupt withdrawal of vitamin C can lower estrogen levels in the blood, increasing the risk of ovulation and unplanned pregnancy - although the data on this subject are few, debatable and ambiguous, the effect of vitamin C on contraception cannot be completely excluded. Please reduce the dose of vitamin C used, and certainly take it with a time interval of at least 2-3 hours from contraception.
