All good signs I hope!

Af isn't due until the 13th, and im 8dpo today. I have been extremely thirsty the last couple of days, and starting yesterday I've had a tingly feeling in my nipples. Also all I want to do is sleep! Napping when I can has become a regular thing for me. I am really hoping that these are all signs to my BFP! I'm going to test on the 15th if AF hasn't came :)
