PINK Spotting what does this means👀👀👀

Artaea
I spotted on the 8th day of my Cycle and I thought it was just ovulation spotting but I spotted again like a week n a few days after n yes I had unprotected sex threw out this whole month and I've been cramping moody n my belly button is tender n I can't hold any food or anything down n I've been having heart burn n I've been really gassy n sore breast... Is that implantation spotting and when is the best time too take an EPT
