Hi! Lately I've started feeling nauseous from the smell of meat in any form. A lump in my throat appears when I smell it. Then it seems to go away, I can eat meat. I have 8 days left until my period, we don't plan on having a child with my husband. The only new thing is that I've been eating healthy for a month and there was some stress.
