Opk help

So let me give you girls a feed back,

I miscarried on December 3rd haven’t started my post miscarriage period. So I have tested for opks through out the days since CD9/11... well this past friday and Saturday I had what looked positive to my eyes my LH surge always lasts for 2-3 days could it be that I did ovulate in between these days? I started having mix symptoms of af and ovulation, boobs are achy, cramping on and off...
