Headache after first light sparring session

Title says it. Been practicing Kickboxing for about three weeks now and had my first sparring opportunity on Tuesday. Light sparring mind you, I didn’t take any hard hits, everyone was very nice to me. I’ve had somewhat of a mild headache since. It’s basically gone today and I’ve had no other concussion symptoms. Just wondering if this is normal for someone who’s never sparred before, maybe my body just isn’t use to it? Not asking for medical advice. If it gets worse or doesn’t go away I’ll see my Doctor.
