Sensitive head/scalp?

KW • Mommy to two sweet daughters and pregnant with a 3rd baby! (don`t know gender yet)
Has anyone noticed that their head is more sensitive during pregnancy? I bumped the top of my head today on a hanging down light in our house (metal but it moves, kind of like a pendant light) and it still hurts 6 hours later. Seems crazy since I didn't bump it that hard! (I am fine - no symptoms of concussion or anything.) Just wondering if anyone else has noticed the same thing.
