Best Answer: It means quite a few things: U/L can mean units per liter -- some medical tests are reported in this fashion. Finally, the greek letter Âµ or mu appears occasionally in science. There is, for example, a subatomic particle called the Âµ-meson. It is used in dealing with very small or weak measurements, such as the Âµ-ohmmeter, and in the measurement of wavelengths. I'm sure there are many more, but I think you get the idea. The term Âµ represents (usually) the extremely small or weak.
Not all women experience implantation cramping but those that do will notice it when the implantation occurs within their womb. The cramping will occur at the same time as implantation, between six and twelve days following ovulation. At this point, your new fetus will be attached to your uterine cavity. Some people say that implantation cramps are natureâs way of hinting to the expectant mother that she has conceived.
When Does Implantation Occur? Implantation typically occurs 6 to 10 days after ovulation, or day 20 to 24 of a menstrual cycle. However, it can happen a few days earlier or later. In an average 28-day cycle, ovulation occurs on day 14 with the first day of a woman's period being considered day 1 in a cycle. Once fertilization occurs, the egg stays in the fallopian tube for three days before entering the uterus and begins to implant itself to the uterine lining.
