Four months of vaginal bleeding, now some rectal bleeding

Hi,

i have been bleeding continuously now since July and have iron Deficiency Anemia which is being treated with 3 iron tablets a day. I have had two ultrasounds which cane up with nothing “sinister” but noted thickness of 16mm with “no discrete focal abnormality”, however the bleeding alternates from light to very heavy. I saw a consultant two weeks ago and was finally referred for a hysteroscopy and biopsy but have not had the appointment yet. I also had the Mirena IUD fitted 5 weeks ago as the doctors kept telling me it was hormonal but that hasn’t made any difference. I have had an episode of golf ball blood clots since the Mirena as well as over the months before. 

I am very scared now as I have suspected for a few months that I may have rectal bleeding along with the vaginal bleeding but have previously dismissed it as pooling from the front. I had confirmation two days ago that it was rectal when I had a gush in the back passage and this was confirmed visibly by blood when wiping and around the rectum. It was also clear by the pool of blood at the back of my underwear. My doctor told me to come back on Monday if I get another episode and she will refer me for a colonoscopy urgently. Tonight I have seen that it could be a sign advanced cervical cancer when accompanied with my other symptoms and I am very scared. Everything is taking so long to get diagnosed. The Gynaecologist couldn’t see the cervix on examination due to the amount of blood present. I am sorry if it is tmi, but I am very worried. I hope it is ok to post again on here.
