I'm underweight and have low body fat. Could this affect my ability to get pregnant?

In brief: Yes

Both underweight and overweight can affect fertility.
In the case of underweight, there is inadequate hormone production which affects egg development in the ovary.

In brief: Low body weight

This is a common belief, but in most cases not so.
Menstrual cyclicity, and thus ovulation, clearly depends on maintaining a percentage of body fat (not known exactly.) thus, women over-or-under ideal weight may have fertility problems related to impaired ovulation. If you are skipping periods due to your low body weight, it's certainly possible - otherwise, unlikely this is a problem.

In brief: Yes

Most underweight women are so by a conscious or subconscious restriction of calories which is sensed as life threatening, starvation stress.
Nature does not want a stressed female to become pregnant due to added stress. Many underweight women are also big exercisers which is also sensed as life threatening stress. The brain decreases FSH thereby interrupting ovulation.
