Bleeding from vagina when I poo

Hello all, I'm overwhelmed with anxiety and have had to wait a very very long time for the relevant tests and I'm hoping to hear others stories similar to mine -here's a bit of background info- 35year old female with 1 child and 2 previous misscarriages. I had HPV for 3 years in a row, had a Colposcopy in 2023 as CIN3 cells were found. I also have an isthmocele niche (internal 5mm pouch) which is as a result of my emergency csection. Currently on Eloine (contraceptive pill) as I've had constant vaginally blood tinged discharge pretty much since the birth of my son who is now 4 years old.

I've had pelvic pain and a constant pressure down below and I pretty much always have the feeling of needing to poo but when I go to the loo my vagina just releases blood discharge which ranges from brown to pink.

I'm now waiting for my appointment for a Hysteroscopy to find out more details about what could be going on.

I'm also due to have a mammogram 26th April as I recently found a painless lump in my left breast.

My mum had breast cancer 23years ago and has just been diagnosed with late stage multiple myeloma.

I am absolutely petrified of the outcome for my appointments and also the fact that my Mum isn't going to be around for much longer. I feel so helpless and have had to go back and forth to my GP for the past 4 years to be referred and was initially told "it's your body's new norm" and it's just been a battle to feel heard. 

I'm constantly visiting to the loo and there is always blood. I know the waiting lists for many of us are terrifyingly long but I really am fearing the worst!
