TRYING not to stress 😫 but need some Help or Advice on my 🌈🙏

So I found out I was pregnant with my rainbow a few days ago. God is so good💕 I had a MC at 5wks in june bled for 6 days and my normal AF returned July 29th and lasted 5 days.

We used ovulation tests and here is Aug pregnant again. Thankful to god we were blessed so quickly. (Praying for those who are having a different experience than us)

I'm at 4wks and some days right now but I'm so so careful in everything I do. I am trying to be excited but I'm also so nervous I can hardly sleep even though I'm exhausted 😩

any advice to manage the uneasiness I feel. I just want my 🌈 to stick so we can have our baby in our arms😭🌈.

Thank you in advance for all the help💕
