Hi yes it is normal - and good.
Post meno bleeding must be checked out.
There is usually a trans vaginal ultrasound test (less invasive than a smear because there's no speculum or scraping), with a gaget like a metal tampon that sits in there while it sends ultrasound waves that allow the operator to see the inside of your womb. If the lining is thickening or there are polyps forming, that can cause the post meno bleed.
I was told that 90% of cases are not cancer, so of course I want the 10% possibility closely examined.
I've been there twice and both times had procedures that were all clear. It's likely I will have others.
A word of warning. If the gynaecologist casually says they want to take a little look and get a little sample - beware. A pipelle biopsy is a surgical procedure and you will need pain relief.
If they say they can see polyps and recommend they pop them out there and then - beware. That is a bigger surgical procedure and you will need more pain control.
I had both my procedures under general anaesthetic - I'm post meno, no children and a stenosed (ie tight) cervix, so I am not a candidate for hysteroscopy (looking into your womb with a camera on a rod) and polypectomy (inflating your womb with water and cutting out the polyps) without anaesthetic.
There is pressure on the NHS to coerce women into consenting to cheap outpatient hysteroscopy procedures. Say no. You have 'Montgomery Rights'.
All the very best
