PMSing 2X a Month??!

Hey everyone, so I read in the Hormonology app that everyone can actually experience pms symptoms 2X a month! I just had my period a week ago(4 days today) and generally pms symptoms begin 7-14 days before I get my period but I am experiencing PMS symptoms right now! This seems way too early to even be getting these PMS symptoms without my period afterwards, but maybe I'm wrong?! Just wanting to know if anyone else has experienced this? They are way less intense symptoms and much more manageable but definitely noticeable!
