Just wanted to mention that a reaction of mtx is severe aneimia. They generally dont infuse until you are below 8. If this is a chronic thing they should be looking at why, and trying to treat that. I dont know your history but some autoimmune diseases cause anemia (I dont think usually that low) but holding off on you mtx may make it worse. Do you have kidney disease or something that is causing the anemia? They should be giving you something to elevate you HgB. Im sure you feel like crap with it being so low. I would say if he didnt tell you to stop it when he told you your hgb was low then start taking it, unless there was a reason you stopped.
Dx: UCTD vs autoimmune spondyloarthropathy vs psoriatic arthritis (ie Limbo x5 yrs) Raynaud's, proteinuria
Rx: Plaquenil 400mg, Ultram PRN, Sulfasalazine 2 gram
