Had ultrasound this morning (day 9 of injections on stim cycle). First measurement of lining said 18mm, she measured again at the end and it was 16.5mm. She said it was very thick and FS may suggest a freeze all...just wanting to hear from others that have had to freeze all due to lining being too thick - what thickness was it? And also hear from those that had thick lining and went ahead with fresh transfer...
