HELP! Looking for some positive feedback

I’m 36 I am 12 weeks pregnant. First baby! 💖 And I am very excited but nervous because every were I read I see that there could be risks for me and the baby because of my age and I’m overweight. I read things like the baby can have Down syndrome and other disabilities and other things can rise as well like me having a high risk pregnancy. I just need some encouragement. Some positive view. The internet sucks!
