Did anyone take work off because of morning sickness and/or being way too emotional?

I'm 7 weeks and my nausea has skyrocketed. I'm a preschool teacher and I had to leave work because of morning sickness and absolutely bawling my eyes out. I feel so guilty for not just sucking it up and working through it all. Anyone else have similar feelings or issues? I know I shouldn't feel guilty but I feel so bad and weak for not being there or just jumping back into it.
