Does anyone know much about womb lining during/after ovulation induction?

[Pepperlypue]

Hi!
I've googled so much but to not much help.

I'm currently in the TWW of our first ovulation induction cycle.
I have pcos so I don't ovulate alone.
On day 12 I had an 18mm follicle & 8mm uterine lining.
I believe I ovulated around day 13 or 14 but can't be 100%.
I went back on day 19 to confirm ovulation & my womb lining was 12.9mm.

Can anyone explain this to me & whether it's a good sign or just normal for post ovulation?

Tmi but we didn't get to dtd as much as I'd of liked, cd12, 13 & 15.

Trying not to get my hopes up as its the first cycle so I'm waiting to test until the weekend but I'm feeling positive.
Any input is appreciated!

I can only give my experience in the context of IVF but yes that sounds normal - my clinic likes to see a lining between 6mm and 11mm on day of egg collection or ovulation - the expectation being that it would continue to thicken post ovulation. Less than 6mm most clinics wouldn't proceed and greater than 11mm 5 days before transfer not great either

Thankyou @bonetiredwithtwins xx
