How do you keep it a secret?

Laura
I have 4 kids (twins 8, girl 3, boy 2). I want to keep the pregnancy quiet as long as possible but at least until I see a heartbeat. I'm with my family all the time and I am nauseous. I look huge after I eat. I'm exhausted. I got caught throwing up at my mom's today and had to tell her and 2 of my sisters. Now I'm wishing I had just stayed home
