Help! I’m going crazy! Smear / bleeding / cervical

So il try cut a long story short, please let me know what you think. I'm in a right state. 
So my periods have always been slightly irregular but I always came on every month-6 weeks 

over the past few months they became really irregular and I would just miss periods. I finally came on, and bled for around 10 days, which is long! I usually only bleed for around 3 days and it's fairly light. 
when I finally came off I was off for about a week, and I had sex and I haven't stopped bleeding since. It's not painful. No cramps. (Even with periods I never cramped, never had any effects maybe just a tad moody) Iv now been bleeding for around 7 weeks. I went in during for my smear, and I explained everything and said my bleeding isn't like a period, it was very light pink and wasn't too heavy. Now it's extremely heavy, and I know this is TMI but, it smells like something is dying. I'm paranoid af that I have cancer.

during my smear the nurse said she could see a growth on my cervix, and I was gonna be sent to see someone through rapid refferal. So I went for an ultrasound and a transvaginal scan. 
they was very nice to me tbh, and refused point blank to give me any information. I know they can't diagnose but I'm already aware there is something there. Anyway I have an appointment with a consutant Monday to discuss the results from the scan. 
today I received my smear results which shocked me a little. So it's negative for HPV. But Iv got to be honest, I always thought smears was to detect cancer not hpv to prevent. How naive. 
so no hpv. Still bleeding. Still paranoid. 
please be honest, could it still be cancer even tho negative hpv on smear results?!

dreading Monday but I just need to know now!
