Delayed treatment??Malpractice???

So I noticed low amounts of (3.53) red blood cells  and hemoglobin(10.9) and hemocrit(32.3) counts on my labs since the second week of janurary I didn't have any idea about this tell I actually LOOKED at the lab report that they NEVER talk to me about or show me.And today I went in and told them how I been feeling and what I been craving which was ice all the time which is called pica . She told me I was anemic and needed iron pills .Note that she didn't not say anything at all what so ever until I approached the subject since she seemed like she had somewhere to be.She said I can take them over the counter or have them prescribed.And I was being rushed again by her because she seemed like she wanted to leave and didn't care much to spend an adequate amount of time with me or address my concerns.And afterwords she rushed me out of the patient room to get some blood work done and I literally had to stop her in her tracks saying I wasn't finished because I had more questions .I needed a doctors note because my job doesn't care much for pregnant women and won't even care to give me a actual break unless I have a doctors note is given (I know they don't have to accommodate me but come on I'm growing a human it takes work !)So I had to stop her for that and the doctor asked said if I wanted to have a note saying that I can't work anymore and I said no I needed one a doctors note for more breaks to be able to have my snacks and water for my needy growing baby . (I still plan on working until about 32-34 weeks)
