"i got my nexplanon in approximately 6 weeks ago and have had no side effects so far! i had a nasty bruise from where the implant was inserted for about a week, but now there is no pain where the rod is and i can easily feel it under the skin. i was on my period when i got the nexplanon inserted, but have not had a period since. no spotting or anything! also have not noticed any particular weight gain or moodiness so far. i would definitely recommend this."
