I had a miscarriage on January 5th. I am trying to find out ovulation again I have had all negative opk tests until this afternoon and they are starting to get close to positive. I test about 3 times a day so I know I did not miss anything. Starting to get ewcm now. I normally ovulate within six hours after positive and normal cramping with it.This temp rise this morning is unusual. Did I ovulate with negative tests? I did have a big temp rise also when I started back temping.
