Wearing pads just in case of bleeding???

Hi,

I’m about 5 weeks 3 days pregnant. Ever since I got my positive test about 9DPO I have been wearing pads in case something happens and I lose it. Is this what everyone does or am I mad? I have to wear light coloured scrubs to work and am terrified of miscarrying and bleeding all over them. It’s my first pregnancy. Thank you ladies
