I just wanted to add:

When we started TTC, I read a book about natural fertility which basically told me that if we couldn't fall pregnant naturally after implementing the book's recommendations, then we weren't doing it properly, and that IVF was only for those who failed at natural fertility (which is technically true, but way to make me feel like cr*p). I beat myself up for months because we followed the book to a tee, and each month AF would arrive and remind me how much of a failure I was. Nevermind that we had male factor infertility issues and that technically, there was nothing else we could do but turn to IVF. You can't argue with 98% abnormal sperm, with a count of less than 5 million.

Since falling pregnant, I've found a few books that basically tell me that if I don't live like an absolute saint, eat only organic, purified, wholegrain, healthy food ALL THE TIME then I'm doing harm to my baby. Nevermind that I can hardly look at red meat without retching, or that hot chips with gravy are all that I can stomach sometimes. I've put those books away now and repeat to myself, daily, "I'm doing the best that I can." I cannot do any better than that, and there's no point beating myself up for not being a saint. My baby will be born to a happy, well-adjusted mother, not a freakish saint woman who never touches sugar or fatty food.

Do the best that you can, and pat yourself on the back for doing it.
