Is this conventional for women use'n the Nuva Ring?

my "friend" was due on monday..and it hasnt even started to show at adjectives, no cramps nothng.and I read that women usen the nuva ring bleed alot for 7 days..is this normal? It's everyday that your body will be off programme for the first few months. You might even skip your period the first month. And your spell will be lighter, not heavier, with the ring.
I be on the nuva ring for over a year and I always started close to 3 days later after I was supposed to. My first 3 months be very stale too, I wouldn't get it until 2 days previously I was supposed to start the clean ring. I never bled a lot, but I did own horrible cramping when my "friend" came. If you freshly started on this birth control your body may just be trying to bring used to it. I found that my periods one and only lasted for 3-4 days when I be on it... it all merely depends on you... everyone is different! Hope this helps you out!
