2nd pregnancy, lots of pressure in vagina/rectum, more frequent urination, more frequent bowel movements (3+/day) occ. Contracts. & cramps. Labor soon?

Not necessarily. Without more information it's hard to answer the question. How many weeks are you? If you are past 34 weeks, these can be common symptoms that are not of great concern, and not necessarily indicative of imminent labor. In general, unless you are having pains that stop you from doing things occurring every 5 minutes or closer, these are likely braxton-hicks type contractions, not true labor.
