Hi and welcome!
Many people choose to get treatment to prevent cobbles and blebs later in life; however, treatment is a personal choice that you must make.
Also, you don't say how old you are, but your insurance (or your parents' insurance) may cover these treatments.
My advice: talk to your parents about your research. Find out if insurance would cover any laser treatments. Consult with a good dermatologist in your area and get his opinion.
Keep in mind: laser may diminish the color somewhat, but won't just "laser off right away." I think treatment should focus on preventing future problems, especially since you seem to have a good attitude about your birthmark (which is a sign of maturity and good self-esteem ... yay you!!).
Come back and let us know how things go. If you'd like to bring your parents by, do that too!
