Hiding bump

Mamas who are already showing, how are we hiding our bumps? I’m 14 weeks with baby #4 and have been showing for a few weeks now, but it’s gotten to the point it’s pretty much impossible to hide without wearing clothes that are inappropriate for the weather - until this point I could pass for just putting on some weight. My previous 3 babes were spring/early summer babes so i was just starting to show in the late fall/early winter with them so it was super easy to conceal with sweaters and sweatshirts. Currently the only people who know about my pregnancy are my parents. I wanted to wait a couple more weeks before telling work or anyone else, so I was hoping I could hide it for a bit longer. I work in a lab, so I wear my baggy lab coat as much as possible to help conceal, but obviously I can’t wear it in the office areas.
