implantation bleeding??????


the toilet paper was from last night around 8 pm(I was supposed to start yesterday) the tampon was also from last night. I put the tampon right after I saw the toilet paper and took it out this morning at 9am. I was cramping quite a bit yesterday although not as much as I would for a usual period. my question is could this be implantation bleeding instead of my period?? has anyone had this happen before???
