Fall during pregnancy

Hi there! I'm about 4 months preg and I actually had a fall earlier whilst trying to stop the main door from slamming shut due to the strong wind. Should I be concerned about the baby inside? Like anything to monitor for? It was a hard fall but on my left knee , so I think It might bruise a little. I haven't told my hubs yet as I don't want to worry him. As of now I just feel pain from the fall 🤣 but not cramps or anything. Pregnancy this time really makes me a little bit more clumsy than usual.🥲
