Sorry about all that you are going through right now but a big congratulations on your baby! There is no better (or harder!!) experience in this world.
I'm glad you have a good relationship with your hubby. You can achieve anything together with that.
My best advice to you is that you are doing too much. In my opinion having a baby is not compatible with working outside the home. You are not only eating and sleeping for two, as well as everything else your body is going through, but you also have a marital relationship. All of this together is more than a full time job in itself. Especially after the baby is born, you will want to be home with your baby. That's your job now. You deserve the opportunity to give that 100%. Scale down, do whatever you have to do, as I said, it's the most important and difficult job in the world.(At one time I would have said it was impossible to be able to achieve this financially but anything's possible where there is a drive to do so. I am now a full time mother and wife and it's the biggest and best job in the world!) And it's your job. No one can do this job but you.You will have no time or energy for any other outside job nor should you try.
You also have a good marriage and that will be more of an effort to maintain after the baby is born. The baby will take so much from you. Don't forget your husband will have all sorts of fears and feelings too.
And about the medication you are taking, imagine the baby being in your husband's body and you worrying about the baby's health all the time. I think it would be so much harder to be the man and completely out of control of what happens and how the baby is taken care of. It is natural for a man to want to take care of his family and this can be a very hard transition. He did sound a little harsh but now is not the time to go to war. This will be a good practice for you to work together on this as you will find many challenges with parenting together and he can be your best asset if you learn to work together.
I don't mean to scare you or sound negative. Having a baby is the most profound, beautiful experience that you will only know when it happens to you. Good luck with it all. It sounds like you have the right stuff to work this all out!
