Confused about a miscarriage

Patient: 5 months ago I had a miscarriage, the doctors said I would of been about 7-8 weeks. My symptoms I had was spitting for a few days then I got a more than a heavy period. It was twice ad bad as a normal period and I had labor pains for over a week not period pains and I had to push out 2 big clots then had 2 small clots come out after than. My question is could I have been further along or could it of been twins my family had a history of losing twins
