implantation to pregnancy!

Angela
Okay lady's!! My implantation calculator said I should be implanting 3rd to the 7th! And cycle day 21 to 24! I've been having pelvic cramping, sharp pains in breast, crying a lot and hot flashes! And cramping in my lower back and abdomen but it is not pms cramps! It's like a pinching/ slight sharp pain. Could this mean I'm implanting and will be pregnant soon??
