No withdrawal bleeding after ipill?

Be

I had my periods from 27th-30th October after I took an ipill on 18th October.

Then I missed my period in November and had sexual intercourse on 1st December and took an ipill again within 3 hours of intercourse.

It's 11th December today and I still haven't gotten periods yet.

I'm paranoid because I missed one period and he also ejaculated inside me.

When should I take pregnancy test?

I'm also very stressed out because of exam season.
