Hi everyone excuse the rant but I've been suffering with these problems for many weeks.

About 14(?) weeks ago I started having constipation, stomach pain etc and was put on several laxatives for weeks which eventually started working after three weeks. I developed an extremely painful pelvis and ovary area where the pain shoot up my back and down my legs. I also had pain and bleeding after sex paired with nausea and a general feeling of unwellness. For a while this was ignored and I was told it was just constipation but once my pooping was semi normal and these symptoms did not leave I was tested for STIs which came back clear. The pain was worsening along with sever bloating every day in my lower abdomen. I was referred for a transvaginal ultrasound which surprisingly to me came back "satisfactory". A new doctor finally decided to see me in person and have a look at my cervix. He said it looks red and inflamed and referred me on to gynaecology. He mentioned a smear but as I am only 20 I was refused this by my GP practice. I have developed lots of discharge often with brown in it which has never happened before. My ovary pain is awful and now I have also severe lower back pain. I do not know what is going on and I am mildly concerned it could be something like cervical cancer that is being ignored because I am 20. Anyone had any similar symptoms or any advice? Xx
