Sorry to hear you felt a bite - ticks are creepy little things, aren't they?
If the head was not inside you and the tick did not attach, I wouldn't worry. Did it look engorged (like it had just finished sucking)?
You may want to keep an eye out for any rash or red mark or anything that looks like a bite.
Also, pay attention to your body. If you run an unexplained fever or you feel achey or sick - get to a Lyme Literate Medical Doctor (LLMD).
Try not to worry - Ok?
Peace and health to you!
