And it just happens so fast
Update! I saw my PCP yesterday. I walked in worried I would have to school him on what was going on. I told him that because I hadn't been very good at taking my supplements, that I'd like to try that. He then said that he'd be willing to do 3 months of prescription iron, but that if that didn't bring it up sufficiently, he wanted me to have infusions. I love that I didn't even have to mention infusions myself.
So, I'm going to be super strict on taking my supplements and doing what I can to get the iron up. If it doesn't work in a few months, we'll move on to infusions to be safe. I'm not actually anemic yet, but the trend is not good, so it's better to be proactive. I really do love my Primary doc.
