Sonogram findings

I had a sonogram done on Saturday.

They found a dominant follicle measuring 2CM or 20 mm and my endometrium measuring at only about 0.5Cm or 5mm :(

Since my findings say that is too thin for conception, will I continue to have this problem? I’ve contacted my doctor but no response yet.

Background: my predicted ovulation was Wednesday, May 3 but did not receive sonogram until Saturday, May 4th. So I seem to have longer cycles than I thought.

Any help at all would be appreciated 😊
