What Premom Ovulation Calculator does in ChatGPT
The Premom Ovulation Calculator plugin opens an interactive calculator in ChatGPT. You enter the first day of your last period and your average cycle length, and it estimates your ovulation day, your fertile window and when your next period is likely to start.
It also suggests the day in your cycle to begin using LH ovulation test strips, so you do not waste strips testing too early or miss the surge by starting too late. The calculator works in English, German and Simplified Chinese, and you can change the dates to see new estimates.
The listing says it does not link to a Premom account, sell anything or send you to another website. The results are estimates based on cycle dates and are meant for learning, not as a replacement for advice from a doctor.
