Is it normal to not have or miss a period on the implant? I got mine in July and had 2 heavy periods a month till November then 1 a month nov-december. I'm 7 days late now and kind of worried my husband and I had sex Dec 3rd (before period) and 31st but he pulled out before he finished both times I know i'm probably just being weird lol but just want to see what everyone else says. I know it causes irregualr bleeding
