"i got the nexplanon october 22nd of 2015 and i spotted for a month and hadn&#039;t had a period since. i had bruising in the insertion area for 3 weeks. the first couple of months i had a killer migraine nearly every day they eventually stopped. as i hit my first year mark i began getting pregnancy symptoms so i took a few tests even went to the doctor and i wasn&#039;t thankfully but turns out all my side effects (nausea, sensitive smell, weight gain, mood swings, excessive sleeping, and even frequent urination) were due to the nexplanon. i finally got it removed january 16th of 2017."
