thin endometrium

Hi! I'm currently undergoing investigations for my recurrent miscarriages. I had a scan on day 15 of my cycle - around ovulation time - and I just found out that the lining of my uterus measured 4.6mm on that day. Consultant didn't mention this to me at all in person but it was in my notes that this was 'a bit thin' but given I've conceived many times before didn't consider it a problem.

I'm not sure what to make of this! It's my understanding that the endometrium should have been somewhere around 10mm at that point of my cycle, and while a thin uterus lining might prevent conception it can also lead to early losses. I'm meant to take progesterone pessaries when I'm pg for exactly that reason so I'm surprised he never said anything about it. I don't know when I'm going to see the consultant again to discuss all this and besides feel very in the dark about it all - generally feeling that the attitude is that I don't need to understand any of this, just let him treat it.

Anyway, I guess I just want a bit of guidance from anyone else who might know more. I just want to understand what's going on and what I can do to improve my chances.

well, that's pretty crushing. Thanks all.

Estrogen is what helped my lining grow thicker. I had it in vaginal pessaries by itself or together with sildenafil (viagra) and it did make a difference. Unfortunately I am not in the UK so I can't recommend a certain brand. My normal lining would be around 6.5, but with estrogen it thickens up to 8.5 or even more.

During IVF cycles it thickened by using a low dose of stimulation medication.

I think you should raise you concerns with your consultant, because a thin endometrium is indeed an issue.

Hope this helps!

Hi Ladycarlotta,

I am exactly the same as you, was told my a fertility specialist that my lining was “too thin” at 4.6mm which was roughly day 14 of my cycle. I have also been given little information on how to fix this before trying to conceive. It has filled me with a lot of anxiety and kind of explains why I’ve had such light periods for years. I am wanting to try for a baby naturally but don’t want to start before thickening my lining. I’ve started supplementing vitamin E as I’ve heard that can help.

would love to hear how you are getting on.
