My wife is 19weeks pregnant with twins.. after having ultrasound test two weeks ago... we received a phone call from doctor's office and the nurse told my wife that they found bright mark on one of the baby's heart.. what does it mean... the nurse told us not to worry... we are very worried..

Congratulations! 2 of my 6 kids are twins.

Take the advice and don't worry. Have you gone back for a consultation and follow-up ultrasound?
