Trying not to symptom spot

I'm 5dpo today and I woke up extremely late and tired from all the intense dreams I was having. I also woke up with a headache. I have a runny nose and I've been sneezing a lot, it could be my allergies but I've been taking Claritin. My body just feels so fatigue and my chest feels heavy. Has anyone else experienced this and got a BFP? Thanks in advance
