Hello, I've been worry about this thing for about two days. I'm only 16, I'm small for my age 4"11. I recently had the implant in my arm and everything was fine until I had sexual intercourse with my boyfriend and during it I started bleeding a tiny bit and a couple of days after, ive been bleeding like a normal period. Just wondering if this is normal? Or did he tigger my period? I didn't think you could go on your period when you are on the implant. I am actually so scared and worried. Please help, thanks x
