real vs bh?

I get contractions a lot and sometimes they kinda hurt and make my legs weak. Sometimes they are consistent in the length apart. But I went to the hospital once because I was scared I was going into labor. I've just been waiting for them to hurt more than they usually do before I think it's serious. So are there any other ways to determine the difference?
