Contraction Knowledge

Understand the science of contractions to better cope with labor

Three Types of Contractions
Features: Irregular, painless or mild discomfort, do not intensify.
Timing: Start after 20 weeks, more frequent in late pregnancy.
What to do: Change position, drink water, rest to relieve.
Features: Relatively regular, moderate intensity, shorter duration.
Timing: Start 1-2 weeks before delivery.
What to do: Keep observing, note regularity, prepare for labor.
Features: Strong regularity, gradually intensify, intervals shorten.
Timing: Active labor phase.
What to do: Go to hospital immediately, prepare for delivery.
Three Major Labor Signs
Water Breaking (Rupture of Membranes)

Sudden gush of clear fluid from vagina, uncontrollable; go to hospital immediately.

Regular Contractions

Contractions 5 min apart lasting 60 s, gradually intensifying.

Bloody Show (Mucus Plug)

Vaginal discharge of blood-tinged mucus, usually 24-48 h before labor.

Three Stages of Labor Timeline
Stage Duration Range Contraction Features Mother's Feeling Notes
First Stage Primipara 6-12 h
Multipara 4-8 h		 5-3 min apart
60-90 s long		 Strong pain, needs breathing skills Conserve energy, void timely
Second Stage Primipara 1-2 h
Multipara 30 min-1 h		 2-3 min apart
90-120 s long		 Strong urge to push, need bearing-down Follow doctor's guide to push
Third Stage 5-30 min Mild contractions Placenta delivery, sense of relief Watch for postpartum bleeding

Contraction Timer FAQ

It is recommended to prepare after 37 weeks. Start timing when you feel regular abdominal pain, backache, or tightening. If frequent contractions occur earlier, start recording and consult your doctor.

Go immediately when: 1) contractions 5 min apart lasting 60 s for 1 h; 2) water breaks (clear fluid leaks); 3) bloody show (blood-tinged mucus); 4) obvious decrease in fetal movement.

This timer uses precise timing algorithms and can accurately record duration & interval. It also auto-analyzes labor signals per obstetric standards with accuracy above 95%.

True labor: intensify gradually, intervals shorten, longer duration, not relieved by position change. False labor: irregular, same intensity, relieved by rest or position change. Timer helps accurate judgment.

Mild: bearable, can talk and move normally; Moderate: must stop activity, short of breath; Severe: unbearable, unable to speak, need support. Choose by actual feeling; system adjusts advice accordingly.

The timer is optimized for ultra-low power. It supports background & lock-screen timing. Ensure sufficient battery or plug in charger before use. Average consumption less than 5% per hour.

Data export saves complete contraction logs as files, convenient to provide accurate data when communicating with doctors, helping them judge labor progress and make best delivery plan.

Regular contractions: intervals relatively fixed (vary ≤1-2 min), duration gradually lengthens, intensity gradually increases. Generally ≤10 min apart considered regular, ≤5 min apart active labor.
