long LH Surge

Carrie
Hello. Quick question- I have always been normal with my monthly cycle before birth control and my husband and I wish to start trying for our second child. My body "went to sleep" according to the doctor and so put me on a 10 day cycle of provera to "wake my body back up" after being on BIrth control for so long. 
I have had a child 6years ago, so I know I'm not infertile and my OBG said everything looks amazing all tests have come back normal and this is the first time trying since that time.
I have had 15 days of a "high" lh surge according to clearblue Ovulation tests. Is something wrong? Just started to have milky discharge this morning and the LH surge is still showing High. I have not had a peak day slight spotting  last week :(
Please does anyone know??? Why would someone be having 15 days of a surfer but no peak?
Thanks everyone!
