Felt AF cramping but now nothing?

sounds like it to me...when i had implantation it was the day my period was due, i was POSITIVE my period was coming, you know those cramps that your soo positive your bleeding? i went to the bathroom and had a spec of blood and nothing the next day and found i was pregnant. implantation to me felt exactly like my period starting...i cramped like my AF for the first 2 months or so
