I watched this when I was pg with DS, and I remember being amazed that I actually got pregnant when I learned about all the crazy things that have to be just so for conception to happen. If it is taking you a few cycles to get pregnant, don't worry! You can do everything right and be totally healthy, and one tiny thing, like the receptor on the egg not matching the one on the sperm, and it won't happen. Don't watch if you are feeling super sensitive/dismayed about TTC right now, but it is SO interesting! Definitely check it out if you are in a good space with TTC and haven't seen it yet.
