i am 24 years old and recently have been experiencing some changes. i have been on the birth control implanon since december of last year, and since then have not had a period. recently my breasts started hurting so i went to the dr and a pregnancy test came back negative. now i am experiencing extreme night sweats, body aches, cramps, and occasional spotting. could this all be from being on the implanon, or should i go get check out again by a different dr.?
