Ok so every month (usually before or during my period) I get 1-3 random days where I have nausea so bad that I feel like I'll be physically sick for a few hours. Sometimes it comes on in my sleep, sometimes in the morning, but very rarely does it come on later in the day. The nausea is always accompanied by a ton of mucous in my throat. I know mucous itself can make you nauseous, but this is a monthly thing, and I don't know if they're connected. Any help would be appreciated.
