Thank you for your query.
At 11 weeks the fetus is only a few centimetres long.
you need to consult a gynecologist and book your scan
the scan procedure is a simple ultrasound
that would be done abdominally now since you are already 11 weeks pregnant.
A woman starts showing in the second trimester after 14 - 16 weeks.
You cannot feel lumps or balls right now, as the uterus
is still a pelvic organ.
You can easily know the fetal sex as early as 12 weeks onwards.
