Possible pcos?

I have two small children but, my family has a lot of women who have pcos. I’m starting to see signs but am unsure if I’m having symptoms or if anyone else has experienced this.

I’m gaining weight, finding new hair growth and my period, which was always regular was a week late last month and a week early this month.

Signs? Or is this just hormonal due to something else? I’m breastfeeding but he is 10 months old
