"i got my nexplanon in may of 2015. i have had unprotected sex twice and have not become pregnant. i have noticed, however, that my period is so unpredictable and can last almost a whole month when it comes but is reasonably light. i wear a pad a lot to ensure i don&#039;t have an accident. my depression and anxiety have gotten worse but i&#039;m not completely sure if that is because of this birthcontrol. i lost weight which wasn&#039;t bad. i have so far liked this birthcontrol and will continue to use it till i&#039;m ready to have a child"
