below are my symptoms. Could some of you ladies comment your thoughts

Natasha • Wife to my best friend. Crunchy mama of a 3 year old boy, Judah. 2 babies in Heaven, one on the way, due March, 2021.
Okay, I'm only a few days post ovulation, but I honestly think I conceived a day before my last period (never mind that detail), anyway. Symptoms are:
Mild occasional nausea 
Bad headaches almost daily 
Light cramping 
Light pain in my left kidney 
Light pain in my left boob 
I've also had what appear to be implantation bleeding 
Does this sound like pregnancy? If so, when can i test?
