Does your partner think that the food you cook smells bad? Do you smell too?
We know that it can be a small consolation to say that "it is completely normal!" But… it's completely normal! A good start might be to find and get rid of everything that might affect your partner's heightened sense of smell and make breakfast in bed. The nausea is usually at its worst right then, and if it comes in a tray with some well-chosen favorite (which doesn't smell bad!), It can be a good help to alleviate nausea. These symptoms are likely to linger until week 12 when they should slowly ease up. And maybe all of a sudden she may begin to appreciate your scent again.
