Insight please!!!

I'm am constantly reading on here trying to compare my symptoms and cycle to everyone else's and I'm getting myself worked up so I figured now is finally the time to ask!  One app says my period is supposed to start the 20th and glow says the 18th.  My periods are frequently abnormal.  This is my first month TTC.  On June 3rd I have a small amount of white discharge and this is the day glow says I was supposed to be ovulating.  I haven't had any discharge since, have taken a test on Monday morning (which was negative), I haven't had any cravings for sweets like I normally do before my period, I have been having extreme bloating for about  a week or so, I have been light headed/dizzy A LOT!!! And I feel my appetite has not really been what it usually is (but no food aversions). I did have a sharp pain in my lower middle abdomen last night and another tiny pain in my left ovary area (for about) 3 seconds the day before!  I would appreciate anyone who can tell me what they think!!! It's quite possible it's all in my head!!!
