Lining thins by 1mm compared to 5 days ago scan.

[kattie22]

HI! A bit anxious here. Hoping friends here with experience can share .

My FET is next Tuesday. My lining today is 8mm compared to 5days ago which was 9mm. My doctor said can proceed because 8mm is the minimum. My concern is if my lining is thining and I still have 3 days to go before my transfer, I am worried that lining continues to thin these 3 days.

can anyone give some advice or share your experience??

one thing I notice, I started progesterone and was given ovidrel shot the day after my scan of 9mm. Are these 2 items going against the estrogen causing lining to thin? Does anyone knows what’s the use of ovidrel before transfer? I heard to mature eggs but how does it help in transfer or implantation? Clinic just told me it’s for hormones boost.

My Anxiety boiling up.

have my fingers crossed for your transfer next week! I don’t have the answer to your medication qns, but I found this Instagram reel from Dr Tim Child super helpful regarding endo thickness - instagram.com/reel/C8FUylFN...

Should be ok even if it drops to 7mm x

My understanding is that progesterone compacts the lining a bit so you would expect it to thin slightly after starting the progesterone x

Thanks for sharing. Then shouldn’t I reduce my progesterone ? Does it make sense if I reduce it so it won’t compact too much the estrogen, thereby keeping the lining intact. Do you know when the lining thins , can it thickens again?

I'm afraid I don't have enough knowledge to say in terms of what happens now with the lining. But I don't think you should be reducing your progesterone - it is an extremely important hormone for IVF treatment

Thanks a lot!

The progesterone can compact the lining a bit. It may carry on thickening or it may remain as it is but the progesterone maintains the lining once the oestrogen has thickened it so you need it to stabilise it and stop it breaking down. The thickness of the lining can vary a lot and they won't normally go ahead if the lining doesn't look healthy and thick enough. Best of luck for your transfer!

8mm is still really good. Loads of studies show even 6.5/7 being good thickness. Good luck.
