Anyone AF Late this month?

Cinnamon
So according to glow I was supposed to start on the 8th of this month and according to my <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period tracker</a> I was supposed to start on 13th. Well here I am 7 days late acne everywhere and my boobs are swollen and tender. I had cramps and what I though was pms -even craving chocolate and that's a big symptom for me!- two weeks ago but AF didn't show. Anyone else In This boat?? I took a test last week but it was negative. I may try again soon. Also having light mild headaches randomly.
