Today is 10 dpo but I got a BFN

All other months of trying, i symptom spotted but this month I don’t even have my normal before AF sore boobs. The only thing is I got the worst wave of nausea this afternoon and it came on suddenly. Since then I’ve had a headache and I’m tired. The past few days I’ve had a runny nose that won’t go away, exhaustion, and very light cramping on my left side. Like I said, all the other months I thought I had every symptom imaginable.

Period is due Thursday..Could this be it?!
