Hi It depends on how irregular your periods are and what is average length of your cycle. I would still recommend to do a pregnancy test a day or two after your expected date of periods , that is example if you got periods on 24th October,  do a pregnancy test around 28th November and then if negative, repeat after a week or so and check again

Irrespective of the unprotected intercourse First on day 31 Second on day 38 from day one of period
