Lining decrease after starting Progesterone for FET?

[bextoliver]

Wondering if anyone has experienced this. I had my lining check on Sunday and it was 1.27 cm. Today I went for my Matris ultrasound to check the quality of the lining and I noticed that my lining has gone down to 1.03 cm. I can’t quite remember but I don’t think this has happened before. Is it normal for your lining to decrease after starting progesterone?

Thanks!

Hi there, yes on my last cycle this happened to me. When I asked my Fertility doctor why she said Progesterone can cause it. My lining had been increasing well and on the actual day of transfer when they measured it has decreased. I was a bit shocked but as I say the doctor didn't seem too concerned and said Progesterone could be cause but it should increase again. X
