Geriatric Pregnancy 👵🏽

Ok ladies so I don’t post often on here but I have been driving myself crazy lately. I am almost 35 and I am 5 week pregnant w/my 2nd. My doctor basically tells me I’m high risk and now I have all these concerns that I didn’t have the first time. Like miscarriage. It’s a constant worry!! This pregnancy has been so different then the first. I didn’t even feel pregnant the first time until 7mo. This time I am nauseous and cramp mildly every day. I know it’s normal but can’t help but worry since I’m geriatric lol. My mind is messing with me! Anyone else having these concerns being an “older” pregnant woman??
