It doesn’t look like you did yet. As per Glow’s BBT page... Once you’ve ovulated, your basal body temperature will shift up by at least four-tenths (0.4) of a degree Fahrenheit. If your temperature stays elevated for at least 3 days after that shift, then you know that you’ve ovulated. If your BBT is elevated for more than 15 days without a period, there’s good chance that you might be pregnant. If your BBT dips after the same number of days, then your period is most likely on its way.
