Amonia Smell After Working Out - Is This Normal??

I am not sure if this is the right place to post this question; however, I figured I would try here. I have just started this weightloss journey and have recently began going to the Gym in the morning to do cardio (Eliptical, Bike, ect..). Every day I have finished working out I have noticed a subtle amonia type smell in my nose.

I promise that I am a very clean person, do not have cats, and have not been bathing in amonia. Is this a normal thing? Am I dying or is it just the fat kid in me slowly melting away?

Any feedback would be greatly appreciated.

Thanks
