Geritol question?

I have my period every three months, it use to be more infrequent than that so it has been regulating itself which is a good thing. So my period should be here 05/15 (the last one being in February) and I was wondering if Geritol has been successful for those with irregular periods because I want to give it a shot. I would love to hear some stories on your experience with geritol. Thank you ♥️
