5 days late 😋😋😋😋

So I'm TTC with my fiancé and I'm 5 days late on my period. I'm so nervous to take a test because we've been trying for over a year and I'm scared of disappointment 😭😭. I thought I was infertile tbh because I have slight celiac disease. I am 21, engaged and been with him for almost 5 years. Anyone had trouble getting pregnant and it just randomly happen??? I'm really hoping I am but I'm just too nervous to take the test!!
