I'm late! I think? Confused.

Nao • I have endometriosis, EDS, cerebral aneurysms, chronic pain/fatigue/insomnia and also osteoarthritis. Everyone should see: Vagina Monologues!
So, I've been having odd symptoms lately so I did two pregnancy tests a week apart. Negative. 
​But...  Still no sign of AF and Glow predicted the start for 5 days ago. 
​Plus, Glow keeps suggesting that according to my stats, I've been ovulating almost every day for the past 4 days. 
​I have no idea what's going on. 
​Does anyone have any suggestions?: 
​My symptoms are not typical for my PMS but similar. Mild lower back pain, fatigue, insomnia, crazy bouts of nausea, constipation, slightly moody, headaches are worse than normal and feel kinda full (probably due to the constipation) but my usual AF indicators that tell me, "pack your bag just in case!," are totally absent. 
​Also, since AF first came back in March (was on depoprovera), my cycle has only been 20 days long so I'm way overdue. 
​Should I get a pregnancy test again....or go to urgent care!?  Lol. 
​Thanks! :)
