Really concerned not sure what to do


So I put a pause on TTC and decided to get the NuvaRing On Tuesday I inserted it and AF Is due the 23rd I’ve been cramping and feeling sick irk if it’s from the ring or could I be pregnant? My doc did not test me before I put the ring in and said to start immediately I’m concerned because we had sex a couple times without protection before I put the ring in should I test?
