when i had implantation at 6 dpo, it felt like nuzzling more than a cramp (it was soo soft) and abnormally low. then an exact hour later that morning, it was the same sensation but very high up. both lasted a mere two seconds. at 7 dpo in the morning (id say around the same time as the second nuzzling happened at 6 dpo so 10 am), it felt like my period was full blown but only for about 20 minutes. there was no blood and i didnt have implantation spotting at all. at 8 dpo, i got my bfp in the late afternoon. i dont remember any time at all that it was painful. i barely had cramps at all that cycle i fell pregnant and i normally have EXCRUCIATING pains on any other cycle.
