Could I be pregnant ?!

This past July i had my IUD removed. I had it in for 7 yrs instead of 5 as its FDA approved for the extra time. I got my period in August, very light and it lasted about 4 days. Now according to my calendar im 2 days late. Could I have gotten pregnant so fast ?! I have a 13 & soon to be 8 yr old. I don’t remember what its like to “feel” pregnant or when is the right time to test. I have been having some cramps.
