Toddler Kicked my bump

So I am 15 weeks pregnant with baby two (bump is already just bellow belly button) and in the middle of moving and I have bumped my belly a few times and my toddler kicked me pretty good by accident while we were playing.  I know this may be a stupid question, but should I be at all concerned? I know baby is pretty well protected but my belly has been sore this pregnancy so I am nervous (I have an appointment on Tuesday and will ask my doctor obviously)
