, when hormones can effect the baby. No other major anomalies have been reported. You have to keep a close watch on the development of the fetus if you want to retain this pregnancy, by periodic sonograms and amniocentesis
for detection of anomalies. Please consult your gynecologist for further suggestions. Good luck.
