Warning vent ahead. Advice welcome

So posting anonymously incase any of the bitches I work with are on here.

So the place Iwork consist of 35 employees. 5 men the rest are women. Everyone there has children with the exception of 2 women who are just 20 and 21. I am 40 years old ttc for over 15 years with no kids. My hours are a little later in the morning because I work later in the evening. I started seeing a fertility specialist in november and started treatments in January. All of my appointments I have scheduled at 7 in the morning so that it doesnt interfere with my classes in the later part of the day. I informed my boss when I started treatments that my appointments would be on days that I couldnt control because they had to be at certain times in my cycle. At most I may have a day or two notice but will try my best to keep themas early as I can because my dr is almost 2 hrs away. I am a hard worker and can count on one hand how many days I have missed in 7 years. So I get called into a meeting and get told that my appointments are getting to be too much and some people dont even think they are real appointments!!!!!!! Now yes I have had to go for alot of bloodwork and ultrasounds because things arent going as they should and the drs are trying to figure out why other than PCOS. So now my commitment to my job is being questioned. A place where their motto is family first. No one understands the difficulties because they all already have kids. Now I am put in a postion where I have had to make the decision to stop my fertility treatments or lose my job. Wtf!
