Part 2: Ovulation Chart Examples & Understanding BBT Shifts

Ovulation doesn’t always follow the textbook—and if you’ve ever stared at your Basal Body Temperature (BBT) chart wondering what on earth is happening, you’re not alone. In Part 2 of our “Help Please! Am I Ovulating?” series, we look at real-life BBT chart examples to show how ovulation can shift, stall, or take a few tries before it actually happens. These visual patterns help you understand your cycle more deeply, recognise what’s normal, and feel more confident tracking your fertile window.

Here are some other BTT chart examples following on from our “Help Please Am I Ovulating” blog. As you can see in Part 1, ovulation isn’t always the same each month and can be tricky to work out when you’re getting started with charting.
