Getting pregnant at 35

Sonic just turned 35 2 days ago and I always said I would not want kids at 35. I know for most woman it's no big deal but for me it is. I'm like I dont want to be an old mom. Or I start thinking, damn when my kid is 10 I'll be in my 40's😱 Well i have a four year old little girl and when I had her I had complications and a c-section. Which my doc already said if I have another it would be a c section again. Which is no bueno because it was a bad experience😞 But I don't want my daughter to be an only child and my husband really wants another. I'm conflicted! But we have been trying for a year and haven't gotten pregnant. Any other ladies feel like 35 is old for more babies or is this just me??
