How did you get an IVF?

So this might sound stupid.. but my hubby and I want to do <a href="https://glowing.com/glow-fertility-program">IVF</a>. For a few reasons. We want twins, but also because it’s been over a year trying with multiple losses 😞 we already have one daughter but after too many losses, this is what we want to do. And yes, we have the money! The OB said it might be easier for me to have it since the will fertilize a healthy embryo then insert them. Anyways, how did you go about it? How long until you got it done? What testing did you do? Was it successful the first time? How much did it cost per cycle? Does it cost more to have multiple put in?
