How to Track Ovulation: Accuracy vs. Convenience ⚖️

There are many ways to track ovulation, but the accuracy can vary greatly 👇

1️⃣ Urinary LH ovulation test strips

✔️ Highest accuracy, about 90–100%
✔️ Easy to use at home and can predict ovulation 1–2 days in advance
⚠️ May cause false positives in patients with PCOS

👉 Clinically preferred

2️⃣ Cervical mucus observation

✔️ Low cost and can help predict the fertile window
⚠️ Highly subjective, with moderate accuracy of about 48–72%

3️⃣ Basal body temperature, BBT

✔️ Can be done at home
⚠️ Only useful for retrospective confirmation, with lower accuracy of about 30–74%

4️⃣ Menstrual calendar / App

✔️ Most convenient
⚠️ Lowest accuracy, around 21%, and not suitable for those with irregular cycles

5️⃣ Wearable devices, such as Oura / Ava

✔️ Error margin is about 1 day, with high convenience
⚠️ Higher cost and requires continuous wearing

6️⃣ Ultrasound + serum hormone testing

✔️ Gold standard, with accuracy of about 95–100%
⚠️ Higher cost and requires physician operation, so it is mostly used in fertility treatment
