Thanks for writing to us.
your periods were due on 1st of November and you had protected sex between 1st and 4th of November.
If you remimber your dates correctly ,then chances of your getting pregnant from this sexual act are nill .
If you have developed symptoms of pregnancy
,go for pregnancy test,if it turns out to be positive consult some gynaecologist who will advice you further course of action.
If pregnancy test turns out to be negative,wait for a week,hopefully you will get your periods, in a week time,as there are many reasons for delayed periods other than pregnancy
Hope I answered your question.
