Pregnant or Ovulating again this cycle?

Ok super confused, no real dark line or postive ov this cycle, just minimal lines and blinky face on CBD. 
​I was on Clomid CD5-9 so delayed ov I know. TTC on dates based on bbt and past cycles. 7 days later slight dark tarry brown spotting. 
​Now 3 days late for period, but lots & lots of ewcm and super super dark lines on all ov test strips (tested with ov strips b4 running out to buy preg test).  Preg tests negative. BFN
Could my cycle just very irregular? Could I actually be ovulating 30 days past last period? This is so weird. Other symptoms sore nipples, very tired, craving chocolate (not my normal pre period symptoms). 
​Any thoughts?
