I have health anxiety and am terrified of having cervical cancer. I started getting intermittent lower back pain on one side about 3 months ago and also noticed some light spotting that lasted a couple of days. The back pain eventually subsided a fair bit but has recently come back (albeit still not as bad as when it first started) and I noticed some spotting again 2 days ago (I only noticed it once. It hasn't happened since). I've just been to see my doctor and she took a swap but I am so worried. I know it is very unlikely as I am only 20 years old and not sexually active but I can't seem to think what else it could be. I also read that back pain usually means the cancer is very advanced which made me worry even more. Any advice? What else could the swab detect?
