So confused and disappointed! :,(

Kaela • Married to my best friend 8/9/14, Baby boy number 1 made his appearance 8/9/17. Baby Boy #2 made his apperance 4/30/19. Pregnant with Baby Boy #3. Being a mommy is what I dreamed of my entire life. 💙
Was supposed to start on the 24th of December, I am always always on time! So I was excited this was going to be my month, I'm a week late and took 4 hpts and they were all negative. Finally decided to go get blood work done today to find out and it came back negative. I dont understand. And I'm not sure what to do!Me and my husband have been trying to convince for over a year now and starting to think it'll never happen!
