I don't know about the exam part, but it is best that your GYN prescribe you the bc. As for the nuvaring
, it's a hormonal ring that you insert into your vagina, it stays there for 3 weeks and then you take it out for the 4th week, that's when you'll get your period. Check out the website it's www.nuvaring
.com. I loved it and I'll probably use it again after I have this baby.
