Should I call out of work tomorrow?

Both my grandparents passed and their burial is tomorrow.

Tomorrow I am scheduled to close my work but I know it's going to be extremely hard for me to function properly tomorrow.

Today was the visitation and that was hard enough. I had today off because I let my work know ahead of time and made sure to tell them I didn't know when the burial was but I probably wouldn't show up for work.

I'm also 30 weeks pregnant and overall super emotional and don't want to possibly break down while at work and not do my job properly..

Thank you for all your replies. The only thing that makes this loss bearable is the fact they went together and are no longer surfing from health issues.

I'll make sure to call my boss tomorrow and inform him I won't be coming in.
