my mom had me get the shot about three months ago because she thought i was having sex with my bf.

she told me that it takes 2 shots over 6 months to start working then after that, i wudnt need another for three years. so basically it wudnt be effective until may.
( when i turn 17 nd my bf turns 18)

i looked online at doctorwebsites and i learned that the shot is effective almost right away or in week and every three months you need a new dose.

i have another doctor visit in febuary ( three months after i got it, ironic mb?) nd i wus wondering if she was lieing to keep me from having sex or not? which is the truth?

i dont plan on giving up my virginity right away if it really is already affective, dont worry but i want to know if i am protected if something does happen...
