Freaking out

I am freaking out. I found out I am pregnant with my second baby over the weekend. I wasn’t expecting to get pregnant so early my son is only 11 months. I don’t have anyone to talk to as I don’t want people knowing. Does anyone have two under 2? Did it work for you guys? Is it a huge adjustment? My OB appointment is scheduled for 11/15/22… I don’t know how I feel yet my first I was so excited when I found out but idk is this feeling normal?
