How much can my lining thicken in a week?

Mi

Today my lining was 5.3mm. I’m probably going to ovulate 4-5 days from now and do FET in 7-8 days (3dpo). My question is can my lining get to 7mm by then?

Every previous cycle it has been over 7mm by this point in my cycle so I’m just worried why this is the month it seems to be going slow. I’m 2 cycles after ER and aiming for my first FET. We are male factor only.
