Congratulations to would be mother, Don't be panic/Woried. Don't think that your new born will get the same problem, your baby is going to be a healthy child. A negative thought in pregnant women will leads to actualization. Be cool, peace of mind,  mild physical exercise, regular visits to doctor, healthy food, good sleep, meditation to your loved god are more important at this movement. Remember first 3 months are very important. Don't entertain negative thoughts. Avoid watching horror movies, and TV serials. Read good Books(mythological,comic etc).
