Of course, it is your first priority to consider all the consequences of the long leave, which pregnancy imposes on you. You must make everybody aware of your leave plans and the subsequent situation.
First of all, you have to decide on the time you plan to take the leave and at the same time think about how that affects your present job. Assess the impact on your colleagues as well. Most of your coworkers may be happy, but some of them may have doubts about your loyalty or commitment to your work. In this situation, you must allay their fears, if any, as early as possible.
When all is said done, the entire leave plan should be very flexible as nothing is in your hands as far as the developments regarding the pregnancy are concerned.

You must try to clear all the doubts and fears of your colleagues before you go on leave than on your return. In your anxiety to please your coworkers, don’t give them an open invitation to call you at any time with any little problem. By all means make yourself available to them, but set limits. You must keep in your mind that you and your baby remain the first priority. You should also check online coaching programs of maternity experts and return-to-work specialists.
