Bleeding issue 4 months post partum

Hi ladies!

I am 4 months post partum.

About 2 weeks ago during sex, I noticed blood on the sheets when we were done. It went away as soon as we were done; and didn't come back... until last night. I wiped and noticed some blood.. so of course I kept aggitating and wiped more, and then this ended up coming out.

It was a blob of pink/grey tissue, on top of a few clots.

I am an absolute nervous wreck. Everything I google says cervical cancer, although I have had normal paps and had a normal cervix check 3 months ago at my PP apt. I am not in pain, and the bleeding has since stopped.

I have an apt at my OB tomorrow morning but wondering in the meantime if anyone has dealt with this.
