"i got the nexplanon around 3 months postpartum. i was exclusively breast feeding and figured it would be easier while everything was suppressed from breast feeding. i had a horrible bruise (but who cares?), and low back pain with crampiness (i expected it). i got a period right afterward which was light, but for 2 weeks. that subsided and i thought i was home free! but shortly afterwards i began to get stressed, anxious, irritable, and angry. i thought i might be pregnant, but wasn&#039;t. that&#039;s when i realized after 4 weeks it&#039;s the nexplanon! i&#039;m getting it out tomorrow. it&#039;s so bad that i&#039;m mean to my kids, made my son cry and i can&#039;t- just can&#039;t be mean mommy anymore. i wish i would have realized sooner it&#039;s the nexplanon."
