Hairspray taste in mouth?

Yesterday I had a taste in my mouth that developed randomly (wasn't eating or drinking anything). It tasted just like hairspray! It was so bad I had to get a mint to make it go away. It and the happened since. I'm 8 dpo today and when I googled it, many women said this was a possible pregnancy symptom. Has anyone had this experience that resulted in a BFP? I've had some cramping and ovulation like pains, I'm really hoping this is our month!!
