Weekly data is often affected by holiday events . The acf and pacf of the original data is often insufficient to identify a good model. Only the data knows for sure. If you post it (include starting date and country if applicable) I will try and help see https://stats.stackexchange.com/questions/406986/sarima-modelling-results-choosing-the-right-lag-for-seasonal-data for a very similar (but different) question. – IrishStat May 07 '19 at 10:09
