Pregnant?

So my period is late according to glow but i have an iud so i dont normally get periods. Iv had the feeling that i might be pregnant in the back of my mind but i haven't had any obvious symtoms, the only symtoms i have had are slight cramping witch are normal for me because i have endo. I dont know if i should go get a test to be sure im only 16 im nervous and scared this is the first pregnancy scare iv had.. If you have any advice or tips let me know! Please dont leave hatefull comments as im only here for support.
