When did you have another baby after c section?

I had a rough time with my first pregnancy and I had terrible round ligament pain, which caused me not to be able to walk starting around 28 weeks until I gave birth at 37w2d.

And at 37 she was born at 7 lbs 5 oz. If she decided to come later, she’d be about 10 lbs. My body couldn’t handle the weight of pregnancy. I’m 4’11” and pre pregnancy weight was 125. I know everybody’s different but my body couldn’t take it.

I 100% want to have a second baby. I just don’t know the right time. They say wait 18 months to get pregnant again, but it’s that enough time?
