Well, I think if your doc says all is good for you and the baby, it may well be that anxiety is flaring because you have broken a management pattern . . . if you are not eating properly and getting some minimal exercise then that might be affecting your sleep . . . . plus have a baby can be anxiety provoking because you are anticipating something that will happen in the future . . .
You say that you have been having anxious thoughts . . .can you pinpoint what these thoughts are about? Are you anxious about having the baby? About the changes that a baby brings into your life and that of your husband? This will help you to decide what actions to take . . . in general, though, not doing anything is not good for anxiety, at least not for me . . . this only increases anxiety but if you are doing something, even if the activities are very small, you are distracting yourself from your anxiety . . . so long as the exercise and what you are eating are fine with your doc, then do something and, not only will it help you, it will help your baby also because you will be moving . . . so, you have been lazy for a couple of days . . . . so what? Pregnancy, even if it is not a woman's first one, still has a lot of hormonal fluxes and impacts so a few days off, fine . . .but now it is time to take care of yourself and while you are doing that, you will be taking care of the baby . . . and yes, doing nothing may intensify anxiety for some folks because it means you are focused on the anxiety which produces more anxiety . . . .
So, check out with your doc the kind and extent of exercises you can do, what you should be eating and a few times giving into cravings is okay but you do need to eat properly to take care of yourself, and, as for the issue of sleep . . . well, mention it to your doc but you may find that with activity you will be tired enough to fall off to sleep but, if sleep escapes you for more than 30 miinutes, get up and do something so you won't be focusing on not sleeping . . . .and if you haven't already tried it, try mindfulness techniques . . . they have been great for me and have helped me readjust my sleep pattern . . .
Finally, never think that your posts are too long . . . . we each need to express ourselves in whatever way it helps and you know this community perhaps better than any understands how sometimes it helps a great deal in just getting our thoughts out into the open . . .so no apologies and when you can, check in and let us know how you are doing . . .. take care, kc
