New here! 8 DPO

Ashley
Hey y'all! I am new here. I am 29 and my husband and I are currently TTC our last baby to complete our family. We live in the Waco, Texas area. He has 2 girls from a previous marriage and I have a son from a previous relationship. This is our second month TTC, I am currently 8 DPO, and I have been so irritable, and moody today and last night. I suppose I may just be really hopeful that this is a super early pregnancy symptom lol!
Anyway, I just wanted to introduce myself! Just here for moral support, general information or Maybe I can find a cycle buddy! My AF IS due around Nov. 28.
I have included a picture of my husband and our 3 children from our wedding day. My world!! 
PS: can someone let me know all of the acronyms, I only know the basics- TTC, DPO etc.
