Common timing mistakes and best practices

Understand the fertile window, not just ovulation day The most common conceptual mistake is treating ovulation as a single appointment that must be met precisely. The fertile window spans several days because sperm may remain capable of fertilization in the female reproductive tract for multiple days, whereas the oocyte remains viable for a much shorter […]

Manual vs app contraction timing and accuracy

Manual vs app contraction timing and accuracy

What manual and app timing measure In everyday use, manual timing usually means using a clock, stopwatch, or notes application while starting a timer when a contraction begins and stopping it when the tightening or painful phase seems to end. The interval between contractions is commonly calculated from the start of one contraction to the […]

How to time contractions correctly and when to start

What contraction timing actually measures Three related measurements are useful. Frequency, often called the interval, is the time from the beginning of one contraction to the beginning of the next. Duration is how long an individual contraction lasts, measured from its beginning until it has ended. The rest interval is the approximate time between the […]

Average contraction duration and how it changes over time

Average contraction duration and how it changes over time

What contraction duration means A uterine contraction is a period during which the myometrium, the muscular wall of the uterus, tightens and then relaxes. Contraction duration is the time from the moment tightening begins until the uterus has relaxed. Frequency or interval is commonly described as the time from the start of one contraction to […]

What contraction spacing means and how close they get

What contraction spacing means and how close they get

What contraction spacing actually measures A contraction is a rhythmic tightening and relaxation of the uterine muscle. During a contraction, the uterus becomes firm and pressure or pain may build; between contractions, the uterus relaxes. The spacing describes contraction frequency, usually expressed as the number of minutes from the start of one contraction to the […]
