Professor expected me to choose cl over my unborn child!!!?

Ok so here it is. I am a full time grad student. I found out I was pregnant after my trimester of cles began. Once I found I was pregnant I started to experience some difficulties, we had to decide whether to follow through with a medically necessary abortion and I was under alot of stress. At this point I was working full time, taking care of a toddler, maintaining a full course load as well as dealing with my medical issues. I had missed a lecture and wasn't sure how many more I would miss due to this and pulled my professor aside and explained straight out my situation to her. I asked her if I should drop her cl or would she be willing to work with me. I was very up front. She told me to continue in the cl, and that so long as I kept her updated and worked along with my ignments I would be fine she would work with me. So after a million appointments and much despair we chose to continue with pregnancy but to tread lightly. Last night I go in to perform my final, and she informs me I missed a test that was not in the syllabus, however it was weighted enough that I would not be able to p the class without the grade and that she was "not inclined" to allow me to make it up due to the fact she felt I needed to own up to a level of "personal responsibility!!!" I am furious and want to contact the Dean. I worked my as* off in that class, which she cancelled half the time, only to have her tell me the last night I would fail?!! I could have dropped and not been penalized months earlier had she not pressed me to continue. I wasted my money as well as my GPA standing will now have a failing grade weighted. I am so upset, I feel like she chose me to choose class over my child, and this from a Master's holder in social worker. Should I report this? Am I wrong in my thinking?
