Can a person have cervical cancer with negative pap smear?

Hi doctor,

I am a 19-year-old female with a weight of 60 kilograms. I have consulted many doctors to know the cause of my issue. I have a list of symptoms such as headache, swollen lymph nodes, chest pain, bone, muscle, and joint pain, low-grade fever, pelvic pain, irregular periods, vaginal discharge, loss of appetite, weight loss, bright bloody stool, constipation, fatigue, and abdominal pain. I have done two CT scans of the abdomen and pelvis. But nothing was shown. I did a transvaginal ultrasound six months back. It does not show any cysts on my cervix. I did a CT scan and MRI of my head and nothing was shown. A CT scan of the throat was taken and nothing was shown.

An ultrasound of the abdomen was taken and it showed a 6 mm polyp on my gallbladder. My ultrasound of the pelvis does not show anything. I took an X-ray on my chest, back and pelvis. Nothing was shown. A degenerative disc was shown in my lower back. I have done all types of blood tests. Everything came back normal. Now, I have a polyp in my gallbladder, a while lesion on my cervix which was found during a pelvic examination, and a degenerative disc in my lower back. I had a pap smear and nothing abnormal was found. CBC, ANA, blood test for RA, lupus came back negative. Lyme disease and Rocky mountain fever came back negative. I can see a trace of blood in my urine. I have lost the urge to urinate. Can I have cervical cancer which is not being found in any scans or blood tests? I do not have any anxiety regarding my pain. Kindly help me.
