"i got my arm implant on may 24th and so far everything was good, no weight gain, headache , no side effects... 
but i was due to have my period on june the 18th, however i started spotting since the last saturday, and it will be a week in about three days.
i started this birth control because i couldn&#039;t remember to take my pills, and i have irregular and painful periods without.
i hope this spotting will not last long, since i will spent two month holidays in the caribbean and i don&#039;t want to get annoyed by the spotting.
sorry for making making mistakes, i will improve my english !"
