Should I see a doctor or is this normal??

I had my period about 2 weeks ago now. But instead of its ending like normal something different happened. Let me explain, My period was flowing normally till day 6 & 7. It just went away but then I spotted again the day after(day 8). Then nothing for 2 days. Then on the third day I went to the restroom did my business but when cleaning myself I noticed a small amount of blood on the tissue paper so I threw it and cleaned myself again and nothing. But I have continued like that since. A little bit of Blood will show on the tissue paper but no where else.?
