Hello ma am and welcome. Please do not get anxious. Wait for a while longer during which the baby will develop further, during this period we can examine the growth and development of the fetus with the help of ultrasound examinations, amniocentesis (if required) and a triple marker test. These should help. Only once an abnormality (if at all) is detected, consider abortion. Because if you go ahead with an abortion now without investigsting further, you may just be held responsible for the abortion of a perfectly normal child. Hope this helps. Best wishes.
