9 dpo bfn after crazy opk surge and faint positive

Amanda • I am 23, engaged to be married, our first is a beautiful 5 y/o angel in heaven, We lost her April 2015, miscarried our second October 2014, we are waiting for our rainbow after the storm. (Ttc 2yrs)
Well yeaterday at 8dpo I got a faint positive, then today with a different brand this morning I got a big fat negative....the only reason I even tested this early Is because 5 days after ovulation my opks turned very dark positive ever single day since...and today I just got my 5th very dark positive opk? Whats happening in there ughhh, I hate not knowing. (The top opk is.my ovulation day on 12/18 & then the bottom 4 is the crazy opk surge, I just got my 5th one today) They are all equally strong. Stronger than my o day.
