I am 44 years old with a 19 year old daughter.
Let me just say you've come to the right place.
I was where you are at 2.5 months ago.
Congratulations and Welcome!
Sure there are risks and your Doctor will point them out to you!
I still think that we worry so much more that we make ourselves crazy in the process of having a baby. But write all your concerns and worries down and when you go to your doctor you can ask them all.
I hope you relax and get all your answers so you can just enjoy your pregnancy!
Good luck and keep us posted.
