I have been diagnosed with mosaic Turner syndrome and isochromosome for long arm of x chromosome. Now I am taking hrt. Doctor told me to take progynova 2mg for 15 days as 1_0_0. X 5 days Then. 1 -1-0 X5days Then. 1-1-1 X5 days After completion of this cycle he told me to take pelvic scan to check the endometrial lining. He told that it should reach atleast 7mm to start with progesterone. After scanning my lining is 6mm. I stopped progynova after 15 days. Then after 1 week of stopping progynova iam bleeding. Why is it so?
