"Geriatric pregnancy" is an outdated term for pregnancy at age 35 or older, sure. Haven't been used by anyone seriously in a while. You managed to Google up some old ass sources, all of them American (surprise) but the rest of the world moved on a while back.
But hey, medically you're living in something of a third world country (not your fault, but it is what it is) so it makes sense that your doctor would use outdated terms I guess. Goes hand in hand with getting 15 year olds pregnant and liking it. She must've thought you were crazy for being so old and all.
You make a big deal of telling us how uncomfortable it makes you, which is interesting since you also seem to really believe 15 year olds are suited to get pregnant and give birth. Can't help but to wonder about these conclusions of yours.
As to your amusing insult, not sure why you'd think eating shit would be a good idea since you're nominally an adult, but it's not really healthy so I think I'll pass and I'd advise you to do the same but hey, you do you. Just don't do any 15 year olds.
