Has anyone who EBF ever noticed/found red like worm in their milk?

Ok so I pumped just an hour ago for LO and as I was putting it in a milk bag noticed a shadowy thing. Curious, I had a look at the bottom of the bottle and to my horror saw a red worm like thing at the bottom of the bottle of white breast milk. Gross me out so sorry if you feel the same when reading this. I then Poured it out on a plate to have a closer look, it didnt seem to move.. so could it be blood clot? Anyone ever experienced this? It was so tiny about 0.5cm (0.2”).
