Concerned about biopsy result

My RE said my endometrial biopsy came back normal even though it says “scattered rare plasma cells.”

“Rare plasma cells are seen on the CD138 immunostain. The presence of rare scattered plasma cells within the endometrial stroma is not specific and not diagnostic of chronic endometritis. Correlation with clinical findings Necessary for appropriate diagnosis.”

Anyone have experience with this? Makes me feel leery. Could this be normal or should I press for more answers? Rest of my RPL panel has come back normal with exception of a high normal (10) homocysteine. I’m on folplex now…just waiting on DNA karotype. All my losses are chemicals.
