I Had The Nexplanon Inserted. After The First Day I

I had the Nexplanon inserted. After the first day I could still see and feel the implant even with all the bruising. Well by day 3 around the implant became swollen and quite red. There is also a light redness around the swollen red implant. I am on day 4 and it is still swollen, red, a little warm, a little itchy and I can't necessarily feel the implant. I know it's under there but it's so swollen and tender.
