Pregnancy Fears

So my boyfriend wants kids, or at least wants to get me pregnant, after marriage.

I love kids, but thinking about what my body would go through freaks me out, like is it worth it? My mom had a very hard pregnancy with my brother and I and one of my aunts is Infertile, so I’m not sure if I can even have kids, I also know we have a lot of health problems.

Are there any moms that went through something like this?
