Sorry for the late response! I wanted to jump in. Congrats to all of you newly pregnant!
I'm 35 and pregnant with my first. Currently in my 27th week.
The first trimester was definitely a time of extra concern! Unfortunately, there are a lot of losses. You see it all over the internet. Googling anything about advanced maternal age and/or the first trimester brings up pages and pages of alarming stats and painful personal experiences.
I find that being older sort of lends itself to a different perspective and maybe more serious outlook on life in general. I would not have experienced the same concerns that I have now about pregnancy and motherhood, when I was younger. Speaking for myself of course!
I was sort of sad to have the realization that life experience has swept away a bit of my optimism. (or, maybe I have a clearer sense of priority-IDK) I didn't really feel like I could get carried away with the excitement of having my first baby, with such an acute grasp on the seriousness of everything. (existential EVERYTHING-everything.) I felt kinda ripped off by that. LOL! Although, it has gotten better as the pregnancy progresses normally and my baby has a better and better shot to survive AND thrive.
I vacillate between joy, excitement, doubts, fears- you name it! Sprinkle in some crazy hormones, and it's really quite a trip. ;-) And it's normal.
People don't often turn to the internet to bear their uneventful stories and experiences. IF they did, you'd probably find a lot more stories about older moms with completely boring pregnancies -birthing normal/healthy babies- than anything else.
I hope that helps to quell SOME of your concerns. I won't even suggest you stay away from "the google".... because, you wont. LOL! I don't!
Congrats to you and the others here! Sending you guys ALL the sticky dust in the world!!!!!! You have every reason to have just as much faith in having healthy and beautiful babies- as anyone else!
