7dpo early signs?

Emma
Ok ladies, need some advice..
Those who have had early symptoms, what where they and how early.? 
I'm 7dpo and yesterday (6dpo) I have nausea, light headness, super fatigue but was waking up around 5/5:30 for the last 2 days. I also had a huge temp spike. 
Last night had strong cramping in lower uterus area. 
Today (7dpo) I've had dizziness all day, on and off, heavy cramps in uterus area and feel bloated. Also I've had extrem fatigue again.
Temp dropped this morning to 'normal' temp range. 
And I making things up in my head or could this finally be our turn.? 
Ttc for 15mnths and counting...
