What were your symptoms?

I’m really concerned I might be having an ectopic pregnancy, I have an appointment tomorrow afternoon but I also have a job interview for a really good position that would change my life and I can’t put my mind to rest. I’ve been on the nuvaring for 6 years and I’ve never experienced this before. I’ve been spotting for 2-3 weeks now, nausea, having some mild cramping and lower back pain, and mostly at night I’ve been having upper back pain concentrated around the shoulder. I’ve taken a pregnancy test and it was negative. My spotting has ranged from red to pink to brown and isn’t any consistent color or flow, like it will almost go away and then come back. I’m sorry if this is the wrong place to post this, and I also want to say I’m sorry for everyone here who’s had an ectopic or loss- I hope you heal physically and emotionally from the experience and thank you for any advice you could share.
