“Coil removal and pregnancy”

I had my coil removed 27th September. I have had unprotected sex every single day 3-4 times a day, my partner has ejaculated every single time. I never had periods on the coil. When would you recommend is the best time to take a pregnancy test as it’s now been 8 days and I know fertility can come back immediately and you don’t have to wait for a period so I’m unsure on when is best to test for pregnancy.
