I am newly pregnant with baby #2. my first is 5 years old

I don't get sick unless I let my stomach get empty or I eat too much. So I just have to have some sort of snack all the time. I am so thankful because I was extremely sick with Lillie the first time around. I lost 15 lbs my first trimester. I have been having one symptom that is extremely annoying though, this discharge that will not slow down. I know grosssssssssss.....but I am starting to think there is something wrong. That is the symptom that is the most bothersome. The breasts are a little tender (not bad), I am a little sleepy and alittle moody. It is kind of hard to explain how I feel right now. It is like I know I am pregnant but I am not accepting of the fact there is going to be a new baby...MY baby here in just a few months. I keep thinking I am going to miscarry or something. I never had these feeling with Lillie so I am hoping it is all situational and will pass. It is very scary not to have any control over what happens.....anyway
She is starting to come around...I hear her playing with her baby dolls and you can catch her talking to her baby brother. It is very sweet!!! She doesn't want a girl though....I think that is probably because all of the new babies she is around are boys.
