Telling your boss & coworkers

Hello! I have been very sick lately with morning sickness 24/7. I feel like I should tel my boss soon since I'm sure she finds it odd all my trips to the bathroom and last week I was out one day because I was so sick. What's the best way to tell her? I'm fairly new here (2 months a newby) so I feel bad telling them I'm pregnant and will be out in 8 months for maternity...thanks!
