If you took off work already, how did you decide?

Be

I feel so guilty thinking about the extra income I could contribute to bills if I keep working but I'm absolutely exhausted by the end of the day. I fell yesterday at work (everything is fine) and am already on lifting restrictions, but honestly these restrictions aren't always able to be met with my work environment and staff availability. I know they should be, but they're not, and it's not that far beyond my limit anyways typically so I usually don't mind pushing it a bit, but when it throws me into a string of painful Braxton hicks then I start to mind. I'm 38+2 today.

The doctor told me today I could take off work at this point if I feel it would be better, but I feel so guilty thinking of going off already if everything is manageable even if extremely uncomfortable. I don't have an actual medical reason to go off, just extreme pelvic pain and other regular discomforts along with this time in pregnancy. I was so hoping to go until I'm in labor but I literally can't accomplish anything at all after working a full day and reduced hours are most likely not an option.

How did you decide when was the right time to quit working?

Editing to add: I'm a substitute teacher so I have no vacation time or paid time off. I also am not dealing with FMLA because I'll just be taking off however much time. In my case, it's not weighing the leave time before or after baby, it's so much guilt more over throwing my +$1,000 in student loan bills and other stuff onto my husband's plate. He's said for weeks he would prefer I go off but I feel like if I can contribute I should, even if its uncomfortable and am just really struggling with justifying the decision because of the guilt.
