pregnant from having sex one day before IUD removal?

Hi all -I'm 31, recently married and just had the Paragard copped IUD removed on 8/17 bc we are ready to try and well, I'm not getting any younger. My husband and I had sex on 8/16 but not again for a week or so after getting it removed. I've been tracking my cycles in eve for about a year and my cycle lengths have been pretty consistent around 29 days for awhile. eve said my most fertile time last month was around 8/16, 8/17, 8/18... And I have read that sperm can live in you for up to 5 days or something crazy... And I was supposed to get my period 2 days ago and I still haven't. Do you think I'm pregnant? Or is it more likely that my cycle is different since I just got the IUD out?? Trying not to get anyone's hopes up but feels a little weird to take a test just yet.
