Confused 😡😡😡

Okay. So my periods (if you count from the day I started it) are ALWAYS 28 days apart. Give or take 1 or 2 days early sometimes. I'm 5 days late. I took a test yesterday that was negative. Symptom wise: I have a stomach virus. Constant nausea, running to the bathroom, overly fatigued. Ya know. The works. I don't know what to do. I called my doc and the nurse said to wait til next week.

I don't follow my app daily. I just use it to track my periods. Well the other day I got really bitchy and my nipples were hurting. So I checked my app *7 days til your next period* and I thought oh I'm PMSing. I did the usual: chin broke out, boobs swole up, bloating, eating myself out of house and home... the works. But no AF.

IM. SO. CONFUSED.
