Fell on ice

So I’m 13 weeks 4 days pregnant currently and I slipping and fell on the ice twice today. Once was just a small fall and the second time (10 min later) was a bigger one. Both times I fell backwards on my butt.

I have had no cramping and no bleeding but I’m still a bit worried. I have a anterior placenta so sometimes it’s hard to find the heart beat for me with a Doppler. I tried to find it when I got home but couldn’t. I swear I felt some movement but I can’t be positive.

Should I be worried? What should I do?
