I don't even know what title to put

I'm sitting here crying and just don't know what I did wrong. All I've ever wanted was to be a mother. After 5 years of unexplained infertility I finally got my bfp and everything seemed so unreal. I couldn't have been happier. I do my best trying to be healthy. I'm eating clean, doing yoga, reading all labels on the things I consumed. I haven't touched any ice cream, deli meat, sushi, fast food, coffee, never even touched a Tylenol although I suffer from SPD, just to find out my baby has IUGR. Although she is fine at the moment all of this is really stressing me out. I don't know what to do anymore. Well that's pretty much it. Thanks for reading. Please pray for us.
