3 weeks pp and huge clot ??

Paige

I had my second csection 3 weeks ago. I stopped heavily bleeding 4 days pp. It's been off and on since then but it's been light and usually brown ish

Today I went to the bathroom and when I went to wipe a massive red clot came out. Like bigger than a golf ball. Along with it came some heavier dark red bleeding.

Is this normal? Should I be seeing my dr sooner than 6 weeks?
