Is there any chance pregnant even if your basal temp maintained the lower range throughout month which shows that is no ovulation due to surge in very unusual?

It is generally not possible to get pregnant if your basal body temperature (BBT) remains in the lower range throughout the month, as this usually indicates that ovulation did not occur. However, there are rare instances where pregnancy may still be possible, even with a consistently low BBT. Here's some additional information to consider:

1. Irregular Ovulation: In some cases, women may ovulate later in their menstrual cycle than expected, which could result in a lower BBT until the actual day of ovulation. If fertilization occurs during this time, a pregnancy can still happen.

2. BBT Interpretation Errors: It's possible that your BBT measurements may not have accurately reflected your actual temperature shifts. Factors like stress, illness, changes in sleep patterns, or inconsistent measurement techniques can affect the reliability of BBT charting.

3.Implantation Dip: In some cases, a temporary dip in BBT can occur around the time of implantation of the fertilized egg into the uterine wall. This dip can be mistaken for a sustained low BBT, making it appear that ovulation did not happen.

4. Luteal Phase Defect: A luteal phase defect is a condition where the progesterone levels after ovulation are insufficient to sustain the uterine lining. This can result in a short luteal phase and lower BBT temperatures, even if ovulation occurred. However, it's important to note that a luteal phase defect typically affects multiple menstrual cycles, not just one.

Given the potential for these exceptional circumstances, it's still advisable to consult with a healthcare provider or reproductive specialist if you are concerned about your BBT and the possibility of pregnancy. They can evaluate your overall reproductive health, assess any underlying factors, and provide personalized guidance.
