Increased endometrial thickness

Did anyone notice that as they became more fertile or more able to conceive their endometrial lining seemed to be thicker? I seem to be having more tissue/clots come out during my period lately. I’m hoping this means that my lining is starting to be of a thickness that could support a pregnancy.

Update:

I haven’t seen a fertility specialist lately as my husband is currently overseas. The last visit I had with a specialist they said all my hormone levels were normal, and I had good egg quality and quantity. Normally my periods are very light and only last about 4 days with almost no lining/clots/tissue being expelled.
