hi ladies, just wondering. hope someone can help me. im preggers with first baby and is a little paranoid about stuff.

any how, i was at dinner today at a restaurant that i didnt realize till after the dinner that ppl around my table have been smoking. they probably did not see i am pregnant since my baby bump wasnt showing. plus my nose probably got used to the smoke somehow that i did not realize until the end of my dinner. its pretty short term exposure 1 hr max. but my har reeeeked of smoke when i got home. how bad is ths?! with all the info i have been reading about 2nd hand smoking its freaking me out! :(
