Metformin Issues

Samantha

hello everyone! i’m currently on metformin for PCOS. from february 17th to around the 23rd i had stopped taking it because of the side effects i was having. i was supposed to start my period a week and a half ago, but i haven’t. is it possible that stopping the metformin for a week caused a late cycle? (i’ve taken two pregnancy tests and they both appear to be negative)

Thank you!
