My 3 month daughter has various "bumps" on her head!!?

She is 3 months old and was born via c-section and her head is slightly misshapen! If you sit her on your lap with her facing forward, her forehead is slightly "raised" to the right! I am wondering if she may have laid that way in my pelvis, I am really worried and I guess you could say that I am a hypochondriac and I am the type of person that worries over "nothing" but this is my child, my life! I mean, wouldn't they have found something on her ultrasound that they took the day that I delivered?! They did a cranial view??! And she has been to the doctors numerous times for her shots and a few other concerns like a blocked tear duck and her well baby checks!! They have always measured her head and no concerns as of yet??!!!! Just wondering! I am just concerned, anyone have this themselves?! Are babies heads all shaped differently?!
