I'm scared of losing my rainbow baby😪

I ended up miscarrying .. a year on Sunday.. at 9-10 weeks. I am currently 18 weeks and 3 days. I constantly think "what if" I'm literally terrified that I get everything all set up I'll miscarry or have a stillborn baby.. my heart is still heavy from my last pregnancy but all you got to do is move forward.. I try so hard to look forward to the positive things on this baby girl I'm carrying and I'm just so scared..ya know? I constantly have been thinking like this since I found out I was pregnant again. I'm so cautious of what I eat , very good at taking my prenatals, staying on top of my health.. I just pray .. I pray everything with this baby is nothing but healthy
