I was last pregnant with my daughter 5 years ago, I had the bizarre craving off smells. I would sit and sniff and sook a sponge covered in baby bath or any kind of bubble bath. The cravings were so strong I would often walk around the supermarket smelling bubble baths lol! Now 5 years down the line I still have these cravings. Not as strong but still with me. Even at the swimming pool the other day the smell of chlorine was heaven. I'm not pregnant, I suffer from depression and take tramadol due to back pain. This isn't normal.
