sonogram today

Had my sonogram today, doc had me worried talking about my lining looked too thick and he was going to give me provera to start a new cycle. Then I reminded him he had me start estrace last week, then he was like oh then your fine lining is coming along fine it is at a 8. Still have to do a lining check next week, but he said I can come during ivf monitioring which is before work and just leave ultrasound with receptionist. All immune testing came back negative. So transfer is still the 14th.
