New to birth control

Hey everyone...

So my doctor prescribed birth control for me so that it will (hopefully, fingers crossed) reset my cycles. I haven't had a period since February, and I'm ttc. Also, I should say that I have NEVER been on the pill or any birth control before, and I'm 23.

Anyhow, she prescribed cryselle. I have been nauseous and puking ever since I started it.

Is this normal? Does it last long? Does it get any better?

Any advice or input is welcome.

Thanks in advance!
