Now, more than ever, you need to be focusing on taking care of you. Don't worry about posting to the rest of us; we're big people and we can take care of ourselves. We'll do our best to throw a little care-taking your way too! So don't feel that you are being selfish.
Be patient with yourself. The hormones and the pregnancy are in the drivers' seat right now. Ask H to be patient with you too. If all else fails, try to remember to treat H as a you would a stranger. This may help diffuse any frustrations you feel toward him or about a particular instance until you can look at it a little more objectively.
And be sure to keep your feet up...no ankle-swelling allowed!
