I feel like I'm slowly bleeding to death while pretending it's not happening, should I "advocate" for myself with the doctors? How?

[questionzzz]

TMI and long. Please help. Nothing like this has happened to me before.

background: 45 yrs F, 2 DC, generally healthy. No former complications with childbirth, reproductive system, periods etc.

So, over the past few years I have generally had regular, fairly light periods, lasting 3 days at most. A bit of cramping and heavier flow on the 2nd day, nothing an ibuprofen couldn't take care of.
Right on the dot 5 days after my 45th bday, I start a mild spotting (last Sunday, to be precise) just less than 2 weeks after my last period. I have a bit of a panic, wonder what going on, make an appt to see family dr but that's not until 20th Sept, continuing to bleed, so on Tuesday I go to walk-in clinic and see dr who examines me, takes swabs and writes up bloodwork, also gives me a pep talk about how it's probably just "life changes".
Call back from dr following day (last Wed) saying the bloodwork returned all normal, even for peri menopause my hormones don't indicate that, so just a fluke. They'll call me if anything irregular
in the swabs, but not otherwise.
No phone call so far, thankfully.
meanwhile the blood flow is getting heavier and showing no sign of stopping.
It's been ten days now I'm bleeding, with some clots, feeling a bit weak and woozy sometimes, but otherwise no pain, no cramps or anything.
Sex last night ended up looking like a murder scene. (dr said I could have sex)
What should I do? Just wait it out? Seeing my family dr on 20 Sept. Should I just wait till then? I feel at this point I'm slowly bleeding to death but not sure what to do?

Get a referral to a private consultant - if NHS won’t do it, pay the £250 and do it privately. It will get sorted in a hour (Tranexamic acid and mefanemic acid or naproxen - depending on your own medical circumstances of course) or mirena etc., don’t suffer with this you can get this sorted very quicky - you don’t have to Iive like this
