Nervous about a cookout..

My husband is in a wedding this weekend and I'm supposed to go to the rehearsal dinner with him tonight. The brides parents are fixing ribs and I think a hog roast. I'm nervous that the ribs will be smoked and not grilled bc I've heard different times that during pregnancy, you should not eat smoked meat bc of how its cooked. I brought that up to my husband and all he said was, "you'll be fine!" ..he says that about everything!
