Hi there folks
I thought members might be interested in the results of a womb scan I had recently.
For those who don't know me - background is I am late 60's, been on HRT for 15 years (approx 62.5 mcg) oestrogen patches), taking progesterone (vaginal utrogestan) 200 mg x 12 days approx on a long cycle (now 6 weeks instead of the usual 4) which gives a withdrawal bleed (not fun at my age!). All approved by my NHS GP.
I had a scan the other day. It was probably about 7-10 days since stopping the Progesterone so the lining should have been fairly thin, though because the bleed was short, the timing was later than I wanted - but it had been pre-booked estimating when the bleed would have finished.
By ultra-sound (U/S) abdominal scan the thickness measured 7.8 mm but surprisingly the transvaginal scan (TVS) which is considered more accurate showed it to be 9 mm. I was quite shocked by this - both how thick it was and the seemingly (to me) quite large difference between U/S and TVS.
However the sonographer said that for women on HRT with no abnormal bleeding they considered the cut-off point at which further investigation should be carried out, to be 10 mm whereas if not on HRT and if abnormal bleeding it would be 5 mm if I remember her correctly.
She could see no abnormalities - she couldn't find the fibroid I used to have (it was under 1 cm previously) and didn't see the need for further action though she suggested I contacted my GP to confirm normal endometrial thickness on HRT.
I had told her that my GP had recommended a course of norethisterone every now and again instead of utrogestan as I was on a long cycle - to "strip" the lining, should it have built up - but I've only done this twice, and not for several years, so I will probably suggest this to my GP. Ideally I would hope they might send me for another scan subsequent to this to check the lining had reduced but these days who knows?
