Anxious - 10 weeks 3 days

Feeling anxious, I slipped and fell on my ass yesterday down a hill, hurt my shoulder more as my husband was trying to hold on to me - now I'm worried I've hurt the baby. I had such a broken sleep last night and every time I went back to sleep I dreamt I was miscarrying. I've had a scan at 7 weeks and 8 weeks, baby was completely fine and had a strong heartbeat. Still have pregnancy symptoms albeit milder but I just cant help but worry. It's getting me so down.
