I sometimes worry if I am making the right decision

I am posting this is controversy corner because some might think it's a controversial. I have been trying to get pregnant for almost a year. But every so often I go through these feelings that maybe I don't want another child. I have one already and I worry about all sorts of things. Money, health, my first child, the work, the stress, the effect on my body. I realize it sounds vain. But then other days I am so excited to have one and wish for another baby. And envision holiday dinners and sibling growing up together and happy times. But other days I go back to thinking about weight gain and sleepless nights and two tuitions, No more lavish vacations Etc.. Am I the only one that thinks this way. Please no judgment.
