I've been taking acetaminophen can this make my period late?

No: This is a new one for me so i'm hoping my colleagues can help you & me out. I have never heard this question so i needed to search online but i couldn't find any evidence of this either. It's been commented on anecdotally but i couldn't find any evidence that Acetaminophen does anything more than reduce fever & pain. In other words, no, Acetaminophen won't delay your period.

Acetaminophen: should not delay your period.
