Norethisterone and late period

Hi everyone

I took the norethisterone tablet last month and started my period 3 days later on the 17th. My app tells me I should have started my period on the 19th this month but it is now the 22nd and I am worried. Should I be worried or has anyone else had the same issue after taking these tablets ?

Thanks in advance!

I has norethisterone in April and since then have only had one period. It was a 72 day cycle in effect. This month I am now at day 50 and still no period but not pregnant. It is very annoying and worrying but apparently normal for norethisterone.
