I Have a quick question!

So I am 10 weeks and 4 days preggernant(lol) and I just CANNOT get rid of this bad aftertaste when I eat something. LITERALLY EVERYTIME I EAT!! I mean instantly after I eat and the bad aftertaste comes I get nauseated!

I’ve tried mouth wash after I eat, cold water , scrubbing my tongue, eating ice cream .I’m scared to try lemon because lemon is already sour .

I wanted to know for first time moms and “familiar rodeo mommies” , what do you do to relief your bad aftertaste/nausea in a natural way?
