I am pregnant. in subway elevator there was a very strong clorox odor. does it harm baby?

No: If it didn't harm you it didn't harm the baby. Your concern tells me you seeing going to be a good and caring mom. Best wishes

Should not..: If this was just a temporary exposure and you don't have any other symptoms this should not cause any problems with the baby. Usually things that can cause damage to the baby cross the uteroplacental(between your womb and baby's placenta) barrier and travel in your bloodstream.If you had severe respiratory issues this may affect the baby by low oxygen supply as a result if that was the case.
