Having a hard time deciding...

Tiphanie
My last day of work is suppose to be July 22nd I will be 37 weeks then. But here recently I have been feeling absolutely miserable, vomiting, nauseated, horrible back pain, constipation. So considering telling my manager today that my last day will be next week the 14th. I've had to call in 2 days this week already because of how I feel, and think that it might be smarter to just quit a week before I was planning too instead of calling in a bunch of times because I'm not feeling good. What do y'all think I should do? I'm due August 11th.
