I JUST NEED SOME OPINIONS

so, i just had my period end last Tuesday (3/13) and had sex that Saturday. but my hubbie pulled out. not on birth control btw. so anyway, now this past Thursday I had a lot of watery discharge, then a few that was like glob of raw egg-whites. & then all weekend I've been having brownish blood like in my panties and when I wipe. yesterday there was a prune like glob in the toilet. what could this be?? Did the sperm meet the egg and maybe not attach to the wall and miscarried?! or too soon? Or could it be implantation?? (sorry TMI for the photo)
