upset is something wrong with me?

Hi everyone, i dunno whats wrong with me, when im with my husband and close friends im alright and happy. Im nearly 19weeks pregnant, on my 16weeks ive finally told my senior manager that i was pregnant and to keep it a secret. This week another manager was looking at me and i noticed he was looking at my belly. Next day he said i heard a rumor.. its in the oven.. i was soo upset.. loads of bad things happened this year at work to me that i dont feel at easy.. but coz im preg and needs the money i didnt bother to look for another job. I dont feel at easy or excited to tell my colleagues that im preg.. buy its starting to show and cant really hide it anymore.. i dunno why im overreacting and so upset.. they all hypocrite at wk that it gets on my nerves.. do you think i strange?
