Questions about TTC?

[2sweetboys]

How do the ovulations test strips work? When do I use them? Where do I get them?

We are planning to start TTC once we get moved in to our new house...(if they EVER let us close!!!!) and I want to be more prepared than just doing the deed! lol

I would like to try for a girl, so any info on this would be appreciated!

Thanks for your help!
