2 weeks late!! Need advice

Ella

Last period was June 20th.. I was suppose to get my period July 18.

Ive taken 5 tests and all are negative.. What's wrong with me?

This is the longest I've gone without my period .. I'm irregular so that doesn't help.. But even then this is the longest my cycle has ever been, ever!!!

I'm at day 52 of my cycle. Only symptom my booobs feel soooo heavy and look darker...
