slipped down the stairs

Meesh 🤰 • Momma to a beautiful 💜 and 2 💙. Last 2 babies born with NAIT. Loving this life.
A few hours ago, I slipped down about 2 stairs. I landed on my butt and one cheek and the arm on the opposite side took the brunt of the fall. I'm 20w3d and I can't help from worrying. At first I wasn't worried because he was still moving. As time has gone on tho and the more I think, the more worried I feel. He's still moving fine, there is no spotting and no cramping. I called the advice nurse and she told me the same thing. As long as there is no cramping, bleeding or loss of fluid, not to worry. She said baby is very protected and I will for sure feel the pain of the fall more than him. Also, I thankfully have my anatomy scan tomorrow morning but regardless of all of that, my mommy mind won't stop worrying. I don't think I've ever had any kind of fall with my first 2 so it just seems so scary.  It does seem to hurt when I sneeze which hasn't happened at all during this little cold.
