I went to the doctor last week for my first appointment. I found out I have twins! But discussing further with my doctor she said one of the babies has a very very low heart rate and one is healthy. I don't know if one of them is going to make it. I'm very nervous I have my follow up appointment tomorrow. Has this happened to anyone?I'm very excited to have one healthy but I'm also really upset because it is not looking good for the other one. I'm lost...
