I just lost my dad

A week ago I lost my dad to pulmonary fibrosis and lung cancer. My family was all there surrounding him when he left us and it was the absolute hardest thing I ever watched, ever have gone through, I don’t even have words to describe it. I miss him so much and am grieving him every single second. On top of that I am worried sick about my mom and siblings who are also grieving this loss. I’m also trying to be as “normal” as I can be with my 2 year old who doesn’t quite grasp what is happening but is definitely struggling too and having lots of major meltdowns and is very hard to handle right now. I am 6 months pregnant and devastated he didn’t get to meet my daughter. I’m worried about how my grieving and stress is affecting my pregnancy. I don’t want to cause my baby any developmental delays or any issues with the birth but I’m not sure what to do to calm down - I don’t think there’s anything I can do. So I’m asking you guys, has anyone ever dealt with a traumatic event while pregnant? Were your babies okay? Any help or advice is welcomed just please be kind because I literally cannot handle any negative comments right now. Thank you.
