Normally Good Smells Disgusting??

Has anyone else dealt with this? I'm 10 weeks, and all of a sudden I can't stand certain smells that used to be good or at least neutral. Like my husband's breath... Used to love it because it was his smell, you know? Now it repulses me and I can't stand kissing him. And even like the smell of my own breasts... Not that the sweat used to smell good, but it was just a natural scent... Now it grosses me out. This is causing problems! Anyone else??
