Understanding cycle characteristics
OvuSense is unique. The OvuCore sensor uses Core Body Temperature to predict ovulation using current cycle data, confirm ovulation, and produce detailed cycle patterns which show what is happening to the level of progesterone throughout each cycle. The OvuFirst sensor uses skin temperature to confirm the date of ovulation. The standard version of the OvuSense App can be used with either sensor to track ovulation, and observe cycle patterns by eye.
OvuSense® Pro provides in-depth cycle pattern analysis, automatically flagging each cycle pattern type identified below, aiding diagnosis and treatment of ovulatory issues.
OvuSense Users can purchase OvuSense® Pro as a subscription upgrade, and then share their data with their doctor if they want to. The user and their doctor access the unique insights of OvuSense® Pro through a dedicated encrypted online portal.

Early OvulationWhat is it?
Ovulation that occurs less than 40% of the way through a cycle. That's equivalent to ovulation on day 11 or earlier in a 28 day cycle. It generally results in a shortened 'follicular phase' - which is the time from the start of the period until the day of ovulation in a cycle.
How common is it?
Wilcox et al. (2000) estimated that 2% of women were in their fertile window by the fourth day of their cycle and 17% by the seventh day (based on 213 women).
Why does it happen?
'Early ovulation' is more common the older a woman gets, and simple things like stress, coming off the contraceptive pill, or a recent pregnancy can also cause early ovulation. However, for some women it's just 'their normal'. Klein et al. (2002) - study size 31 explains that the pattern of shortened follicular phase is more frequently identified in older women due to earlier dominant follicle selection as a result of hormonal patterns.
How can I see it?
'Early ovulation' is easy to see using OvuSense due to its real time ovulation prediction and 99% accurate ovulation confirmation. When 'early ovulation' is found, OvuSense® Pro automatically flags this for the user and their clinician.
What does it mean?
It's not necessarily a problem or associated with infertility, but if ovulation commonly occurs very early in the cycle it is something that needs to be discussed with a fertility specialist. Early ovulation has also been found to correlate with a history of recurrent miscarriage - Jukic et al. (2007) - study size 201
What can be done about it?
Having sex in the first days of the cycle after the period has ended is not common for all couples, but will help improve chances of getting pregnant if ‘early ovulation’ is occurring. If that doesn't help with conception, a fertility specialist may recommend drug treatment to 'even' out the cycle and cause ovulation to occur later, and they can also help advise on reducing the risk of miscarriage.
