Strange clot like thing during period

[user1491242213]

Not sure if this is posted in the right place tried family planning but think here more suitable.

Hubby and I have been trying to get pregnant for a year or so now we know it probably won't happen naturally as he was treated for testicular cancer several years ago. My period was 11 days late, I had done two tests both came back negative. Today it came though I noticed what I thought at first was a clot on the pad however it had no resemblance to anything I had experienced before it was loose on the pad as aposed to the usual sticky bloody discharge. When I wiped after using the toilet there was another one it was hard and when I used toilet roll to have a closer look it snapped in half and was white inside. Sorry for tmi both were about the size of a 5p but lumpy if that makes sense.

I have used dr google and can't find anything like it anyone got any Ideas?

Thanks

I think it's called a decidual cast.
