"i got my nexplenon inserted about 5 months ago. i stayed on my birth control pill for a month after to help my body adjust and everything was going fine. i had 2 normal periods and up until about a month ago everything was running smoothly. my mom and boyfriend have noticed a big change in my attitude noting that i&#039;m becoming more &quot;bitchy.&quot; can&#039;t say i disagree with this as i can tell i get more annoyed and on edge about literally everything. not only have i been having attitude issues but my acne is out of control right now. i&#039;ve been on my period for 4 weeks now and my acne continues to get worse. i believe i&#039;ve also gained about 10 pounds in since i got the birth control and am having a hard time losing it. planning on getting itremoved."
