My boss and my pregnancy?

i told my boss that i was pregnant and reacted really rudely to it. She made me feel really bad for even telling her and yeah i know a lot of it is my hormones but it really upset me. She didnt act this way for the other girl who is pregnant. This is my second pregnancy and it made me feel so dejected and unimportant. What is the best way to deal with this? Please any opinions would be appreciated because i dont know what to think about her reaction. Thank you
