Advice needed

This can't be it, can it? AF due yesterday. Not using opk or temping this month so o is based off glow. These all seem normal for me aside from the loss of appetite -I'm usually a ravenous beast and the cm (ib?)  also my skin is usually terrible but nothing this month? 
1-14dpo very sore boobs 
10dpo tiny pink tinged cm crampy
11dpo no appetite, cramps near ribs 
12dpo exhausted, low appetite
13dpo no appetite tiny amount pink tinged cm cramp left ovary 
Am I over thinkin this? If anything I'm experiencing less symptoms than usual. Moods much more stable..
Thoughts, ladies? Any advice would so be appreciated.. this journey is so isolating
