Thanks for your query.
The above ultrasound
finding is perfectly normal. There is nothing to worry about it.
Normal upper limit of ET- endometrial thickness is 5mm in post menopausal women and 10mm in premenopausal women.
Since your ET is 3mm, its completely normal.
There are two positions of uterus
anteverted and retroverted.
Anteverted uterus is the normal position of uterus.
Hope this helps.
