Sudden stop while driving

My husband and I were driving yesterday and he had to suddenly stop to avoid a car in front of us that stopped short. We didn’t crash but I’m still concerned of the effect the sudden stop or seatbelt pressure might have had on my baby. I’m 16 weeks. I’ve had no signs that anything is wrong so I don’t feel like I need to go to the hospital especially since it was just a sudden stop. I did send a message to my doctor (they’re closed today) to see what they think. I’m trying not to worry especially since I have had no pain, bleeding or signs anything is wrong. Anyone else experience anything like this? I’m just trying to calm my mind. If you comment please be nice and try not to freak me out more!
