"i just had my implanon inserted in march and since then i have had one period and it lasted 2 days. i had previously suffered from severe pms and had horrible cramps, fatigue, and back aches, but now, i have none of that, probably because i haven&#039;t had a period except once. every now and then, i will get what could be considered a period (dark discharge) but other than that, everything is great. i highly recommend it to anyone young and doesn&#039;t want to worry about condoms or pills. it was a great choice."
