Hi Blayz,
Good luck with your meeting with the nurses. I find it very good to talk to them and make sure they know this is your first time too. Ask them as many questions as you can - it will make you feel less nervous if you have a bit more clarity about what is coming up next.
I'm a week ahead of you on the BCP (not birth control pill - i call it the bl@@dy contraceptive pill!!!!). Only because i am a chronic migraine sufferer and all those hormone ups and downs aren't good for me!
I hope you feel comfortable to ask any questions you like here - although the nurses are great - there is nothing quite like the support and advice from people going through the same thing.

Good luck and hope this cycle goes great for you!!
