Etonogestrel
"Hi I'm 21 years old and got this arm implant fitted about 3 weeks ago I've not had any serious side effects only mild bloating nausea and minor headache I was meant to get my monthly period on the 25th of May how ever now its the 3rd of June I've still not had a period yet. I'm about 9 days late. This product is good for regular periods just hope my body behaves its self because I'm away on holiday soon for 2 weeks. Every body is different people react differently to these arm iMplants but I've had no issues as of yet."
