I told my boss that I plan to get pregnant soon and that I'll probably be out of work with HG again. He already knew I planned to do it eventually, but I had to make arrangements with disability insurance and terms of my job.
He was perfect about it! They will support me and accomodate me. I asked for leave without pay and for them to pay my health insurance--and for me to have a job to come back to. He agreed without hesitation. I am so emotional about preparing for more HG in general plus my concerns about work that I started crying when we were talking. I am not one who cries easily and I am really embarrassed, but he was very sweet about it and told me I shouldn't be.
I'll get over the embarrassment, and I am SO HAPPY and SO RELIEVED that things are going to be okay in terms of work.
