Baby looks good but they found "sludge" in there with him. Seems like it makes me higher risk for pre term labor which I already am because my son was born at 29 weeks. I haven't had any bleeding like I did last time so I thought this pregnancy was going smoother. Guess not. I'm so depressed now. I'm only 16 weeks. If something went wrong now he wouldn't survive. I just want to get to 30 weeks.
