Your BaZi is not very good and the Ta Yun is not helping. At work you might face obstacles and can be stagnant. There is not much you can save.
Your name will not affect your husband much. Changing the name will help psychologically but if others still calling you by the old name it will not help. It will be better to look at your house fengshui. Normally when we are in bad luck, it can be shown from the environment. Make sure this is not suppressing you and your husband and making it worst.
What I don’t understand is if your main concern is your husband, but you want to use your BaZi to see what is going to happen to him - better to get his BaZi done.
For baby, you will still have to wait.
Cheers.
