Hey ladies, so I went in for my lining check and they wanted it to be at least 7mm but it was 6.95mm

Is this going to be an issue? They have told me to keep taking my normal dose of Progynova orally plus add 1 tablet twice a day vaginally (didn’t even know you could do this) and come back for another check in 4 days. What can I do to thicken it in the meantime? Are there any foods that help? My lining has always been really good in the past, never had problems with it being too thin so just trying to think what could have caused it?

Thank you for all the advice as always ❤️
