contractions

With my first I always had contractions on my right side only— so weird but that’s how it was... I don’t remember feeling the tightness cause the lower right pain side was always so bad. Right now I am definitely having contractions nothing too painful like I can talk through them and all but my stomach is so hard but not the very top and not the very bottom just the whole center on my body and I know it’s not baby just pressing up against my belly because of the pains I have and the consistency of them. Is this normal??? Should I be worried? I really can’t remember the tightness I had with the first, just the pain
