Any one relate?

Kodee • Army wife and hopefully soon to be mama of our first🤞💕

So I'm 18 dpo, af was suppose to start on Christmas and ive not had it yet. I've had mixture of emotions like heartburn, emotional, headache and fatigue. I just had my iud removed in November. Do you think its a late period or possible pregnancy? Ive taken two tests and both negative. Praying its our time!
