Hello,
A thickened endometrial stripe will not make one appear pregnant To give you some frame of reference, a thickened endometrial stripe might be considered at width of >15mm in a pre-menopausal
womanWomen's way. This does not affect the overall size of the uterus and thus would not mimick pregnancy. You should probably see an ob/gyn to be evaluated for why you are amenorrheic.
Best regards,
