Hi I Have Had Protected Sex On The 9th And

Hi I have had protected sex on the 9th and 31st of October with my boyfriend and I hadn't got my period all of that month, it is now the 6th of November and on my period app it says my next due period will be the 27th of November. I had been quite stressed in October so maybe it could be stress that made me miss my period but I also went through spotting in October. I really don't want to be pregnant and is there any hope this is not pregnancy?
