What is the effect of taking the post-coital pill and vitamin C together?

Patient's question:

No

Doctor's answer:

Okay, here is the translation following your instructions:
Can be taken together. Irregular menstruation caused by frequent use of emergency contraception is recommended to switch to other contraceptive methods in the future, such as condoms. Currently, you can wait and see. If necessary, you can try taking Xiáo Yáo Wán (Free and Easy Wanderer Pill) and Wū Jī Bái Fèng Wán (Black Chicken White Phoenix Pill). Wish you good health.
