Hey there, I haven't had endometriosis but suffered through super heavy periods, cramps bad enough they put me in a state of shock basically and low ferritin levels. I got an endometrial ablation in March as an alternative to a hysterectomy. I'm already sans gallbladder and thyroid gland so I thought I might want to keep this organ :-). I have no idea if it is of any help for endometriosis but my Ferritin levels came up from 4 to 41 in 3 months and I was only getting in two iron pills per day vs. the three they wanted me to take. I now have a "panty liner period" and no cramps. Have they told you not to take iron within 4 hours of calcium (or thyroid replacement) as they bind up together? No one ever told me that as I struggled with my ferritin levels and they wouldn't come up. I take calcium in the eves to keep the restless legs under control so I could sleep and was taking all my iron at the same time so I wouldn't have to deal with the upset stomach. Also iron is best absorbed when taken with some vitamin C. I didn't go the iron infusions route, it was offered to me but Doc said I could go either way, as I have heard that there can be allergic reactions to it and I have allergies and sensitivities. If anyone was going to react I figured it would be me! Doctors visits are exhausting and frustrating, I agree. I had a rule of no more than two appointments per week for myself and tried to prioritize. I have done phone appointments with my PCP on a couple occasions, too. Hang in there! Sandra
