Hi woodymom,
don,t worry. I advice you to see the doctor and check with the ultrasound. usually as early as 6 week gestation,your doctor can use ultrasound to detect any intrauretine embryo.
BTW, I think having a baby is a gift from God.I have friend who had tried very hard, including surgery. in order to conceive.She is now still in vain.
Don't worry for your boss, he or she cannot fire you.
