I didn't know about producing more saliva! I might have had that but was so busy with hand itching, I didn't notice. Ya, that was one for me. My hands itched like crazy. I wanted to go outside and scrape my hands on the bricks on the side of my house! Doctor told me it was a pregnancy thing some women get. It was so distracting, I can't ell you.
I had the smell thing too. I do like broccoli but when pregnant . . . if I was within 100 feet of it, I knew and it gagged me from the smell.
very heightened sense of smell! Sometimes it made me sick
