Scared to get pregnant again?

Is anyone else scared for number two? We tried for 3.5 years for baby 1 (rainbow baby) due to pcos. I had a pretty great pregnancy until 38 weeks when my bp went up. I had a great labor and delivery and now a wonderful little girl.

She’s 14 months and I’ve been thinking a lot about a second child. I keep pushing it off (I need to take medicine to ovulate) because I’m terrified something will go wrong! I’m just a wreck about it! Is this normal?

Also, I’m 35 so time is ticking as well. I want a second baby, I’m just so scared!
