Milk clots helpppp

Alyssa

Little.dude was born sept 11th. Ive been exclusively pumping (long story, flat nipples haha) Ive been getting milk clots coming out pretty much the whole time.. they dont hurt really, and ive just been straining them out with a stainless steel strainer so he doesnt get them. Any ideas as to why they keep happening? They range in size from a penny to a loonie ish soze.
