MC or normal

When should I worry? I felt like my period is coming but I went To pee saw some light blood in toilet then I wiped it was light pink. I put on panty liner and nothing is there so I went back to wipe and it’s light blood literally not enough to cover tissue

I’ve been cramping but it’s mild and now I have gas which is making my stomach weird is it normal?? I’m 6 weeks I’ve been stressing these past weeks so idk. I just wiped and there is no blood on tissue. Is this normal last pic is me literally wiping to see if I see blood
