I think you should ask yourself if you give up your career for your baby, will you think this is a regret? Be frank, I love my baby so much and I want to spend more time with her also. But if this put a ceiling to my career, I think this will also be a great regret for me. Hence, I've tried to squeeze my work in the weakdays and spare the weekend for her. Surely, I need full support from my husband that he can assure me he spend more time with the baby when I'm away.
However, regarding health, I think nothing is more important than this. Without health, without strength, you can neither take care of your baby nor pursue your career. If you are exhausted at the moment, I think you should take a long break to restore your health condition and give yourself sometime to think through.
