I understand this topic has already been covered by others, but regarding this situation I'd like a personal fresh input. My best friend is in her first trimester, bordering her second. She works a very physically demanding job, but it's something she enjoys so stress isn't the issue. What's the issue is that her husband passed away and thus, she's providing for her future child alone. Which is why she's going for as long as possible without taking maternity leave.
I can somewhat understand due to her work being one she enjoys, but due to it being quite physical (she's a martial arts instructor as well as a fitness instructor), I worry about over excursion. I'm qualified in first aid, but would like to know signs and symptoms if she begins to wear thin. I worry for her, taking on so much by herself since her husband passed. I want to make sure she's okay.
