lots of early pregnancy signs

Brandi
Yikes!!! My LMP was 1/6/17-1/11/17
I ovulated from 1/14-1/20 and had intercourse everyday since I stopped AF
On 1/20, my breasts became very tender and cramps very lightly every day.
I also noticed when I squeezed my nipples I had white and clear stuff come out!
My first day I can test is Saturday 1/28!
Just wondering if anyone else has been through this?! 
I don't know if I'm really pregnant or my mind is playing tricks!
