Yucky taste in my mouth!?!

I have such a yucky taste in my mouth it's horrible & makes me feel more sick. I just can't seem to shift it, eating strong cheese gives a small bit of respite but I do find it's making any food taste different.

I bought mints to try to help but I think they make it worse.

Any of you lovely ladies have this too? I'm just wondering if it's a pg symptom or just me being weird.
