Question for you ladies?

So I'm currently 6 weeks and 6 days pregnant, working a full time nursing job (3 12hour shifts) I have a step daughter who's 2 1/2 that my husband and I have full custody of. I'm experiencing extreme neausea and I can barely go to work, I've been calling off work and leaving work early due to the extreme morning sickness. My question is how do some of you ladies do it?! It's so stressful dealing with working, watching a toddler , getting sleep etc...
