"i got my first nexplanon in 2013, for the first year and half no periods at all. then all of a sudden i started getting them again. sometimes every few months, sometimes for a month straight, but it doesnt really bother me. i do have mood swings occasionally. i&#039;m tired a lot but other than that no issues. so i recently got my second one put in, although it hurt when the first one was taken out,and i have a nice size bruise; ive not had any issues yet. i have had weight gain but that just started a year ago and it could have been change of job (desk job now)  or im getting older and i just cant eat the same junk i use too."
