Implantation dip???

Ok ladies please help. So I believe I ovulated the 15/16 of Jan due to cm and positive opk. I do get multiple positive opk each cycle but they don’t always coincide with my cervix and cm like they did this time. So any ways. My temp Alonso rose after that as well but then today about a week later is took a drastic dip! I’ve been reading and read about a implantation dip. Has anyone had this and been pregnant. I’ve also had mild cramps today as. No bleeding that’s I’ve noticed yet though.
