Prenatal vitamins make AF late? True?

Paige • 👮‍♀️💪🏻🏋🏻‍♀️⛸🍜🍣

Has anyone experienced taking prenatal vitamins and having a late period as a side effect? I am 4 days late and We are TTC so I’m hopeful, but the early test I took on the first expected day of AF was negative and I have yet to try again—I am scared i won’t get a BFP!
