Try to keep a record of your contraction. Be patient!
DURATION: Feel your abdomen and record the time the firmness is noted and also when it feels relaxed. This is usually 15 to 60 seconds in length. FREQUENCY: Contractions are timed from the beginning of one to the beginning of another contraction. This is usually noted in minutes. Be sure to time several contractions in a row and notify your physician when they do appear to be occurring at regular intervals.
