issues with my boss..desperate for words of encouragement

i am 14 weeks pregnant with my first baby and newly married since June. i work in a local government office on the smaller side so we definitely miss someone when they’re gone. However, in the last 3 and a half years that I’ve been there, there have been at least 6 coworkers go out on maternity leave, so it isn’t unheard of or uncommon at my job since there are a good amount of younger women working there.

Either way, i was still nervous to tell my boss because i am basically her assistant. To make things worse, two weeks ago, she announced that SHE was pregnant. she is due two weeks before i am.

A few hours after she announced, i was in her office and she kept going over things for me for when she’s out, so i figured I’d better tell her immediately. I did, and i apologized for the terrible timing, and her reaction was worse than i ever imagined. I didn’t get a congratulations or anything. All i got was a sarcastic “great.” Then she walked out because she “had to pee.” For the rest of that week and the week after, she completely ignored me, had other coworkers do the tasks i usually do for her, and just treated me extremely differently.

She is finally now starting to treat me somewhat normal again, however there are still a few things she does that she would never have done before, such as sending another coworker to a meeting instead of me, or not offering me overtime opportunities.

Anyways, i haven’t announced it to the rest of the office yet and i almost don’t want to, even though i know it has to happen soon, so people can know that BOTH of us will be off at the same time. But she has made me feel awkward, embarrassed, and almost ashamed of my pregnancy with the way she is treating me. I just feel like with how she is reacting, that means everyone else at work is going to talk behind my back and treat me the same way she is.

I would really appreciate any advice or even just word of encouragement. How to handle this? I don’t know... i just need some confidence to be able to go to work and proudly announce my pregnancy.
