Can I use tampons yet?

I’m so tired of bleeding and pads! I think my period came back already (last time it just was kinda all in one for 8 straight weeks) this time things slowed around 4 weeks pp and then came back and sorta stopped about a week ago (just had light pink discharge sometimes) and now I’m back to bleeding more red and brown, tmi but stringy (pink/red) and sludgy (brown) at times. I would prefer to use tampons now. I’m 8 weeks pp on Friday. Is it safe yet? Tia!
