Pregnant? Sick?

Abby • Future Ultrasound Tech👩🏼‍⚕️

So lately I haven’t been feeling like myself. I get bouts of dizziness and nausea where I feel like i’m going to pass out, I get dizzy after I eat at times, I have back pain and pelvic pain, and the smell of some foods makes me sick to my stomach to where i almost vomit

My first thought was pregnancy but i’ve taken 3 tests and they were all negative.. but I just feel pregnant.. or something else is wrong??

Could it be an ectopic pregnancy? Could I still be pregnant and be testing negative?? Any thoughts ???
