I was diagnosed with polycystic ovarian syndrome about 4 months ago, placed on birth control, and had blood tests done. The results showed pituitary hormone abnormality, for which I had an mri, however this test came back normal. I was also diagnosed with insulin resistance and placed on glucophage, however was unable to tolerate it due to extreme nausea. I continued to bleed 7-10 days each cycle, spaced 2-1/2 to 3 weeks apart with clots measuring up to 4 cups in volume each day. My initial blood work showed normal hemoglobin with high red blood cell counts, which could have been the first symptom of anemia. Two weeks ago, I became very short of breath and went back to my gynecologist for more blood work and a change of birth control pill. My platelets were abnormally high (500 with norm 150-300), my hemoglobin was again normal, however this time my red blood cells were abnormally small (possible second symptom of anemia), and my iron levels were 27 (norm 40-150). My doctor immediately placed me on aspirin and iron therapy and sent me home to followup in 1 month. Today I went to the emergency room after becoming extremely light headed and short of breath after passing a huge clot. I was told to go home and followup with my gynecologist next week. My question is: shouldn't someone be checking the cause of the bleeding rather than putting a bandaid on it? I've never had an ultrasound or scope performed. Thanks in advance.
