Need transfer day help!

Katie
Our transfer day is Monday(6/27). I have a few chronic health issues that are under control but have given cause for all of the doctors to suggest a single embryo transfer. However, I know that if we did a double embryo transfer, that our odds of conceiving are higher. I've heard several stories of couples transferring two embryos but only having one stick.
We are leaning towards doing a single embryo transfer but I do worry about the stickiness of it.
Any advice would be great.
Thanks!
