Birth Control?

So here's the sitch. I am in some desperate need of birth control. I have one beautiful little girl, but that's enough for me (at least for now) So I'm gonna break down my issues and if you feel like you can suggest something, don't hesitate to throw it at me.

1. The Pill--Ortho Tri-Cyclen KILLS my sex drive. That's not the kind of birth control I was looking for (disinterest).

2. The Shot--Ortho Evra gives me cysts. I don't know why. For the most part, they're harmless, but every so often one of those little mofos ruptures and its hell on earth.

3. The Patch--I'm hesitant to try this because my sister developed DVT while using it.

4. Condoms--They suck. Nuff said.

Does anyone know anything about Mirena or a similar IUD? I understand the inherent risks (PID, etc.) but I'd like to hear from someone who's tried it--how's your sex drive? Any unexpected weight gain or crazy mood swings?

OR

Nuva Ring--any comments/testimonials/warnings?

Thanks Ladies
