2 lh surges?

Lisa

This is our first time ttc, and I was previously on birth control before hand so I decided to get an opk to try to help figure out my cycle. Started on 10/30, everything was low. Until about 11/7 and 11/8 it said was my peak. About 8 days later, it starting to say I'm rising again, but not another peak. Did I do something wrong or what could it be? (I didn't test between 11/12-11/14 because I thought it was over)
