People develop kidney stones because: 1  Their small bowel absorbs too much calcium. 2  Their diets are too high in calcium or another mineral. 3  They have intestinal problems.  Urinary tract 1  infections. They may have inherited a certain disorder that makes their bodies more likely to form kidney stones.
1 Delayed ovulation may be a sign of poor egg quality. 2  Even if fertilization occurs, with delayed ovulation the endomtrium (uterine lining) has aged since the beginning of your cycle and may no longer be ready for the implantation of the fertilized egg.
A woman with a short cycle, for instance, could end up ovulating shortly after she stops bleeding. So if you have sex on the last day of her period, itâs possible your sperm could stick around long enough until her egg is released. Which, of course, could lead to pregnancy. Plus, if her cycles are erratic, she may confuse the start of her period with the light spotting that can occur during ovulation. And if you have unprotected sex during that window, well, that's prime baby-making time.
