Pregnant with a 6 month old!

Shelby
I'm 8 or 9 weeks pregnant (wont know for sure until my ultrasound tomorrow) and I also have a 6 month old son! I've been so sick and I'm not going to lie it's stressful. Anyone else accidentally get pregnant directly after having your first?
Ps. This picture was taken a couple months ago he was only 4 months
