How many mm does your uterine lining grow each day before ovulation?

My uterine lining was 6.5mm on day 14 of my cycle. I will give the hcg trigger on day 16 and have iui on day 18. Does anyone know if my lining will become thicker by ovulation? My RE says he likes to see the lining at at least 6mm but prefers 8mm. I didn't even think to ask him if it will continue to get thicker! You girls help me out all the time, so don't let me down now! Any help or advice would be great! Thanks!

I'm not sure what the rate of growth is for the lining, but it should continue to grow until you ovulate, so it sounds like you still have about 3 more days! Best of luck!

I too am not sure what the rate of growth is but i do know that the uterine lining is created by estrogen . The more estrogen we have the thicker the lining will be. Mine was 9mm 2 days before trigger and 11mm on the day of trigger.
