Early Symptoms ???

Good morning ladies!!

So me and my SO have been trying for 4 months, I’m 8 days before my expected period give or take could come earlier. This would be my 3rd child 🤞🏼, I know it’s too early to take a pregnancy test, but lord do I feel like I’m already getting symptoms. I woke up this morning feeling nauseous, headache, cramping, && obviously my temp. Is elevated. Normal for me is 97.3, it’s been 99.2 the last couple of days. Has anyone else had symptoms this early and tested positive??
