Overly Anxious

Hi everyone, I’m currently pregnant with my rainbow baby (17 weeks and 5 days) and the pregnancy has been going well so far. However, I am constantly panicked something is wrong with the baby and I fear my checkups. I’m also now starting to worry about things like preeclampsia, Gd, etc. after reading the recent ProPublica report on maternal mortality in the US. Does anyone have advice for those of us suffering with anxiety and pregnant with our rainbows? I’m not sure how to calm myself down. Any advice would be appreciated.
