Awaiting Tests - Uterine

Hi all

I hope you don't mind me posting in here, but I feel I have far too many additional questions, on top of what I've put my poor consultant through already, that I wondered if anyone could possibly spare a couple of minutes to advise on?

To keep it sweet, I'll bullet point where I am and how I got to this point:

• Begun periods aged 12, now I've just turned 40
• Never had children 
• 2 years ago I believed I had a UTI due to lower back pain and frequent urination (however, I do drink a fair bit of water, and only started doing so around this time) results came back clear, GP sent me off for CA125 blood test along with pelvic ultrasound, which ruled out ovarian 
• Irregular periods begun a couple month after this. Before, ive Always been on the dot, light periods, little discomfort and menustratee for 3-4 days at a time 
• Periods are now longer (longest was just shy of 3 weeks but avg around 7 days) are alot heavier (more recently with large-ish clots, some times quite painful, but not with every one 
• I get on avg a period 2-3 times a month 
• Sometimes I have brown/brownish red mucus that has a very faint smell 
• History of CIN3 in 2005, with HPV on my medical notes from 1996, but GPs unable to determine which virus 
• More intense mood swings and low mood 
• All tests came back clear for infections 
• Been referred to gynae (the referal got lost in translation, and I ended up having a smear there due to pain management) had smear last Mon, but had an irregular period so they're unsure how good the swab will test 

Due for smear April last year, but GP wanted me to have my  investigations done at same time at the hospital, so that's why I'm so late in finally getting it done.

Been referred for a hysteoscopy 21st Feb  

During my smear, I felt such pain (despite having gas and air) during it. I can only describe it as a burning sensation, but apparently at the time of that happening, the nurse wasn't actually doing anything! Anyone else experienced that before, as I never have, and what could be the reason? 

I'm not in a sexual relationship so unsure if I would suffer pain during, and wondered if others experienced similar burning during smear and intercourse?

I know I live in la la land, but I never get scares whilst undergoing investigations, so I don't want people feeling the need to sugar coat. I am aware of the worse case, and until that's confirmed, I really am not worrying. I found a lump in my breast the other month, which turned out to be a few cysts, and during the whole process, despite me fearing the worse, I never felt anxious or worried (which is weird for someone diagnosed with generalised anxiety disorder and OCD...the irony!)

I haven't lost any weight, other than through dieting, and Xmas has put pay to that...oops. I do suffer odd bout of constipation, but I have a slow gut transit, as diagnosed 2 years ago. 

Any help, advise or similar situations, would be much appreciated.. .and to all of you, I truly hope you are all doing well, and want to see I'm full of admiration for the strength in which you all show....a credit to the human race
