has anyone ever had a light period and ended up being pregnant? the first day of my period was regular and heavy. my tampons were filled up and then the second day it was so light. i changed my tamping regularly and there was almost no blood in it. even after i slept i woke up and there was like no blood in the tampon. my periods are always super heavy. now it’s just super light, i change my tampon like once a day and i didn’t even sleep in one last night. is it possible to be pregnant and it could just be heavy implantation bleeding? thanks!
