Pregnant or just period?

TMI Pregnant? Or just period?

** Last week I had some bleeding that lasted for 4 days some pains here and there but I usually get my period for at least longer than that this was abit heavy but not as heavy then I thought. It was a mix of light pink / bright red

** Couple days after my period flew by I started having a lot of burning discharge with brown / pink blood in it very unsure what the cause of that could be?I will post pictures to show just in case it could be implantation bleeding... I will test today.
