How do you know if you want kids?

Hi ladies,

How can I tell if I want kids? I am an anxious person and pregnancy really really really scares me because it’s painful uncomfortable and so many things can go wrong. The thought of not knowing what will happen to me makes me really afraid. I don’t particularly feel too much adoration when I see babies around me but everytime I hear people I know announce their pregnancies I want to cry, I feel overwhelming sadness. I also always want to do things with my family so my sister thinks it’s because I want kids and to have a family of my own. I am married and have been for almost 5 years. How do I know if I actually want kids and am just scared or if I don’t want kids and just feel sad because I want to want that. I’m very confused. Anyone been in this situation and can give me some clarity?
