2 surges??

Sarah

I had o date predicted for the 11th. I got my OPKs in the mail late so tested Monday the 9th. Lots of EWCM, tested almost positive, then the LH dropped, so I figured I missed the surge and ovulated early. I had no test lines after that, only control lines for a few days, but lots of EWCM. My cervix dropped and turned firm. Now today, cycle day 21, I have a surge again. CM mostly gone. Any takers? Did I have two surges? Why is it so positive?
