I’m so worried

I’m currently pregnant with baby #2 15w+5 last night my almost 4yr old daughter was sleeping on my bed bcz my husband was working night shift. Some how she landed her leg on my belly in her sleep. I was in deep sleep and woke up with shock and a slight cramp after that. This could hurt my unborn baby ?? I’m so worried.. need advice

UPDATE-

Just received a call from my nurse. She said not to worry unless I have blurred vision headache,bleeding or any discharge. And told me to drink lot of water which increase the amniotic fluid level which protects the baby.. thanks everyone for commenting..!
