HELP!!!

Hi my name is Stephanie I am 24 yrs of age. My wife and I are TTC and we had our vaginal insemination on the 23rd. According to my calender that was the day I ovulated. Today is the 8th day after that day and yesterday I started bleeding. It wasnt alot but it was alittle to much to be considered spotting. There was also a small clot and a squishy pink peice of flesh. Today I only have brownish discharge that only shows when I wipe. Can anyone tell me if I should be concerned or is this implantation bleeding?
