Q. I’m in my late thirties, and my husband and I have been trying to conceive for a little over a year. We’ve been seeing a fertility doctor for a few months now, and I recently had an endometrial biopsy. The very next day I found out I was pregnant. The doctor said there’s a slight chance the pregnancy will terminate as a result of the biopsy. I’d like to know how great that chance is.
A. The chance of your pregnancy terminating because of the biopsy procedure is extremely small—I’d say less than 1 percent. The biopsy is a very small sampling of the tissue lining the uterus. The pregnancy would only terminate if the embryo actually wound up as part of the biopsy specimen. But the pregnancy is so small at that point—microscopic—that it would be like finding a needle in a haystack.
