How does this make sense???

So, I started taking prenatals 2 months ago, and my period was always irregular, but since taking them my period has come on the 20 th for the last 2 months, I have always heard that prenatals cannot regulate your period, but unless my body was really needing the extra vitimans then it is regulating it. Also since taking them I have developed 2 more of the pesky(coarse) chin hairs bringing a total of three :( what are yalls insights
