Implantation bleeding or period

Frances

Ladies I know this question is asked alot, but I was supposed to get my period today. I started spotting very lightly around 12, but it's not like my normal at all period. I would normally by now have soaked through a number of pads or tampons. However it hasn't even touched the pads, but definitely there when I wipe. Sorry tmi. It's not as light as it was this afternoon but still not touching new pad. I have been pregnant twice and both times ended in miscarriage but never had this before. Please help. Any advice? Should I just be patient? Also to add I have been having dull cramps yesterday afternoon and the whole day today.
