Anyone here DOES NOT want kids?

I'm 24 and having the hardest time of my life. I am getting married next year and I am 90% sure I don't want kids. People usually say : " oh you will get over that" but quite frankly, the whole pregnancy/mom thing is just not for me. I'm afraid of things changing in our relationship and with myself. Plus I don't like kids , I don't care for them. I don't care to be in pain or wake up every 2 hours to fed a child.

I can't wrap my head around motherhood. Anyone going thru the same?
