I agree that your sense of smell can escalate. I lost my baby in my 2nd trimester but before that, I had a lot of nausea and all day puking off and on, even if I knew we had to go to the underground garage to get in the car, I would start retching just thinking of the smells down there. I also could NOT look at any food pics that were pale. I was having trouble getting food down but I could somehow eat chunky beef Campbell's soup but I couldn't stand looking at the pic of the chicken one of the can.
