How do you decide whether you should go in when sick?

I’m the type to call out only if I believe I’m very contagious and if I’m in a ton of pain. I started a new job at the beginning of the month and had to once. I was up all last night with intense pain that I’m pretty sure is an ovarian cyst rupturing. I think the peak of the pain is gone now but I really feel like I should go to the ER, but I have work tonight and feel pretty bad calling out again since I’m both new and it happened 2 weeks ago. There’s an on call server scheduled, and my shift isn’t for 6 hours. Don’t know if I should hold onto hope that I’ll be good enough to walk around tonight or if I should prioritize my health and go to the ER. I’m mostly worried about the image this gives me and how it affects me staying with the restaurant long term.
