Nexplanon (arm implant) first period bleeding

Cierra

Ok so I had my baby on 4/29 and had my implant put in on 5/28, still hadn’t had my period since baby at that point. I got my period on 6/2 and expected a normal to light period bc the OBGYN said I would most likely stop having a period due to the implant. I’ve been heavily bleeding for 8 days now with one exception of 1 day I didn’t bleed at all for about 12 hrs. Does anyone know anything about when this “period” will be over ☹️
