Hey girls! I'm pregnant and my taste buds are gone, I can't taste anything anymore. After each pill I have to brush my teeth because of a strange taste in my mouth like I swallowed hay. Is this normal for everyone? I thought it would go away but it hasn't. Sometimes I feel like I can't breathe through my nose at 17 weeks. I open my mouth and breathe quickly. My doctor checked me out and everything is fine!
