Is it possible that my delay is due to my taking folic acid?

Folic acid does not affect the length of the menstrual cycle.

A delay can occur following an episode of illness or vaccination, stress, fatigue, change of schedule or even without any detectable reason. I invite you to test every 3 days until you get a positive result or your period starts. If the delay reaches twice your cycle, you should consult a doctor as a precaution.

I will remain available if you have any further questions!
