Stephanie...........this type of situation makes me so so mad.

Legally you must be given time off for your appointments in connection with the pregnancy, as you know.

But like you say, whilst you are being given the time off, there is nothing to stop your employer/boss making you feel bad about it. The fact that he is intimidating you regarding this is terrible.

My advice would be to make an appointment with your boss, and explain, and document, all of the reqirements of the appointments, drive times etc etc, detailing exactly what you have in your post here really!

In this way, whilst he may not like it, you have more than fulfilled your responsibilities to your employer, and you are also making it clear to him that you will not be intimidated, and you will still be taking all the time you need for the appointments.

As you say, they will only get more regualr from here, so set your stall out now.

Do you have an HR department? If so, my suggestion would be that you document the conversations you have at a meeting with your boss, and email both him and an HR rep with all of the details, so that EVERYONE is clear on how you are approaching the time off required for the pregnancy.

Don't feel intimidated, don't offer to go on maternity leave early if you don't want to.

BEST OF LUCK!
