Coming from someone who's been GF for 12+ years and TF for 6+ years, I think it would be easier to just cut out breads, etc. in the beginning.

It can be difficult and frustrating to make tasty GF/TF baked goods, with the exception of pancakes (more on that later). The usual recipes and commercial mixes are very dependent on various types of gums, which aren't traditional or (IMO) healthy. For lunch and dinner, it's easier just to have soaked whole grains such as brown rice or quinoa, or starchy root vegetables such as sweet potatoes. You can create an infinite variety of side dishes by using various cooking liquids, combining different grains, adding vegetables or spices, or using different cooking methods such as baking, steaming, or frying before/after cooking. Vegan cookbooks and web sites often have good recipes for grain dishes, and of course you're free to make TF adjustments, such as adding in some animal fats (or even putting a steak on top

).
For breakfast, soaked GF oats and cream of brown rice are yummy, esp. with fruit. We usually make our own cream of rice, using a grain mill. IMO the grain mill is a must-have in the long term, as fresh flours and meals are much tastier and less likely to be rancid. In the short term, though, Bob's Red Mill is a good brand that's widely available. Just check the freshness date on the package to make sure it's far in the future, and always store it in the fridge or freezer.
It's also quite easy to make GF/TF pancakes, either with sourdough, or soaked with some kind of fermented milk. There are a bunch of recipes out there, and most of them are relatively foolproof. (Things are busy around here right now, but I'll try to add some links when I have a chance.) They'll work with brown rice, oats, sorghum, or pretty much any other kind of grain, and they're especially good if the flour is freshly ground. In addition to having pancakes for breakfast, you can let them get cold and use them for sandwiches, or let them dry out in the oven and use them as crispy flatbreads.
As far as commercial flours go, the ones from
Authentic Foods are finely ground and free of cross-contamination, and they're packaged in foil so they stay relatively fresh. Bob's Red Mill would also be a reasonable choice, if that's what you have access to. Again, check the dates on store-bought flours, and once you buy them, keep them in the freezer.
Since you're just getting started, if you want to have "regular bread" as an occasional treat, I'd just use a decent quality, whole-grain commercial GF bread mix (Bob's Red Mill, Pamela's, etc.) for now. The quest for a delicious GF/TF bread is a long term project for many of us.
Most of all, don't worry if you can't do everything perfectly... nobody can, and it's important to relax and enjoy eating, esp. when you're pregnant.

But do try to go easy on the grains and starches, even if they're high-quality and properly prepared. Many people have triggered a latent gluten intolerance by eating too many grains, and they often continue that pattern after going GF. You're better off focusing on other nutritious and tasty foods, of which there are many on a TF diet.
