First picture of baby.. Feeling scared!

Melissa • I`ve had 3 preg I lost the first then had my rainbow baby then I lost my son this year trying for baby 4(1 living child)
I'm afraid to get excited and become attached to this baby since I lost my son at 17weeka this feb... I cried like a baby when I heard the heart beat! 130 bpm?
Added a bat signal for fun? praying for this rainbow baby! ??
