have you tested with opk's more than once a day to be sure you didn't miss it?? I am thinking I am not going to O either- maybe too soon to tell- but all of my opk's have been light- in the afternoon I get a clear line but no where near + .. it's been close to 3 weeks since my d&c and started the opk's just this last week- so maybe I missed it or maybe it didn't happen.
