OPK not matching body signs

I have been tracking CM and position, cycle days, symptoms for months with no luck of BFP. Tried the strip OPK last month and was unsure i was reading the results correctly. Switched to digital this month and it went from low to peak skipping high. It also said i was ovulating 4 days prior to my tracking. Now i have the symptoms of ovulating but the OPK is back to low. Has anyone else had trouble with OPK? Do i trust the test or my body?
