Early symptoms

So the last few days I have been feeling super nauseous with a dry/ watery mouth, I have been getting tingling in my boobs and almost like pins and needles in the nipples today. I'm 8dpo I haven't had any spotting just wondering if anyone has experienced symptoms this early before and also I have been absolutely exhausted I can barely drive the 10 minutes home from town without thinking I'm going to fall asleep
