8 weeks pregnant /cancer

So I’m 8 weeks pregnant I struggled with infertility for 6 years, my husband and I were working with a fertility clinic to help us conceive and we were successful after 6 iui and 2 embryo transfers i finally got pregnant. It’s supposed to be a really happy moment and it was till they gave us the news my father has cancer. Honestly I’m so devastated I can’t stop crying ,I can’t sleep all I think about is him . It’s hitting me the most because he lives with me and we are pretty close to each other . Every one tells me to relax for the baby and I’m trying but there’s moment where I can’t and I start crying I want to talk to my boss and ask for some days off because honestly I can’t keep it together but I’m afraid they’ll think it’s too much to ask for I just want couple days to process the whole thing , talk to myself and help myself get out of this . Do you think it too much to ask for at work ?
