Missed period!?!?!

My husband and I have been trying for a baby for almost 2 months. My period is Late by 38 days. Every pregnancy test has been negative, and my ovulation test also show no detection. I had my son almost 3 years ago had the iud for almost 2 years and then was on the pill till beginning September when we started trying. I stopped my period with the iud and then I had it with the birth control pill but now that I stopped taking the pill my periods stopped. I don’t know if I should call my doctor
