I've had the rod in my arm for contraception. When I had it inserted I had been on my first period since birth for 4 days. Ive been warned about the contraceptive rod causing irregular bleeding and now it has been in 10 days. Im bleeding but I'm unsure whethery period is just lasting longer cos it's my 1st. Is it normal to bleed for longer than 2 weeks with the first period?xxxx
