Starting Ivf need advice

I want to start <a href="https://glowing.com/glow-fertility-program">Ivf</a>. We stopped <a href="https://glowing.com/glow-fertility-program">iui</a> after 6 fails. We have MFI. Problem is I’m a nurse I work 3 days a week 12 hr day shift and I just started this new job. Can I take a leave of absence this early to go through <a href="https://glowing.com/glow-fertility-program">Ivf</a>? I’m not comfortable telling them my fertility issues and would like to keep private. I need help figuring out how to make it to my appointments and work or if I have to take a leave? Anyone have advice or experience with this situation? I don’t know how to approach the situation. I want a baby so bad been trying almost 3 years. Starting a family is mor important to me then anything .. please help
