Anxiety advice

Hi

Back in July I had bloating, occasional pain in abdomen, feeling full or not eating much, so went to doctors who asked to check ca125 blood test, it came back only slightly raised at 51. So was referred had an ultrasound (external and internal) which were clear and sent for ct scan which luckily came back clear. Was told to recheck ca125 level in October and if normal nothing more would be done but if still raised would require more investigation. Eventually got results to say still raised 53 so only gone up a tiny bit. Hospital have said I'm on a waiting list but probably won't be see till Jan/Feb obviously I'm very anxious about why it's still slightly raised and still got same symptoms. So just wondered if anyone else has had a raised ca125 level and it has been something other than ovarian cancer? 5 years ago I had thyroid cancer so unfortunately I always fear the worst. Any advice would be appreciated. Thank you
