Need advice please

Hello everyone. Just need some advice as my mind is going crazy!! I had cin 3 in 2013 and had lletz performed and have had clear smears since. Recently I have been to doctors and after an internal exam have been referred for an ultra sound scan as the doctor could feel ‘a Lump’. I’ve had some symptoms such as lower back pain, abnormal bleeding and what I call womb ache constantly. My newest symptom which has happened twice now is vaginal bleeding during bowel movements. Has anyone else had this??
I’m a little worried as I know my body and know something is not right. The doctor mentioned fibroids but can’t find whether this happens with fibroids.
Has anyone ever been diagnosed through a scan for fibroids??? Any advice would be greatly appreciated. Thank you xxx
