Late af!

Kristyn • I am a mom of 3 daughters. Married to my dh for 7 years. And ttc for our last child and hoping for a boy. Also I’m a full time nursing student and per diem cna.
I tested at 9,10,12dpo and all bfn! Af is 2 days late and I am fatigued, have a cold, headaches, increased appitite, frequent urination. I am so worried to test. I won't allow myself to even buy one. My luck I'll buy the test and start af the same day. :( just need positive comments ladies.
