AF due tomorrow..but hoping she doesn't show up

hey ladies!!! AF is due tomorrow...i have had nausea, been very tired, my breasts feel huge,heavy,and slightly sore,bad headaches,and my CM was watery. Today, my CM was a good amount and kinda milky. Could this be early pregnancy symptoms? I am praying that I don't get my period and have a BFP when I test next week. we are trying for our 3rd child...i don't remember the symptoms I had with my first two! Anyone else experience this?
