Presence of contractions that occur more frequently than every 2 minutes or last longer than 90 seconds in the presence of late decelerations. Requires repeat testing on following day. [1] Equivocal—Unsatisfactory: Fewer than three contractions occur within 10 minutes, or a tracing quality that cannot be interpreted.
In the early follicular phase, uterine contractions in the non-pregnant woman occur 1–2 times per minute and last 10–15 seconds with a low intensity of usually 30 mmHg or less. This sub-endometrial layer is rich in estrogen and progesterone receptors. [3] The frequency of contractions increases to 3–4 per minute towards ovulation.
Most commonly, Braxton Hicks contractions are weak and feel like mild cramping that occurs in a localized area in the front abdomen at an infrequent and irregular rhythm (usually every 10-20 minutes), with each contraction lasting up to 2 minutes.

The latent stage, when the cervix is dilated less than 3–5 cm along with regular contractions, can last as long as 20 hours without being considered prolonged.

[2]: 73 Also, the repeated-bout effect appears even after a relatively small number of contractions, possibly as few as two. In one study, a first bout of 10, 20 or 50 contractions provided equal protection for a second bout of 50 contractions three weeks later.
