Too close to tell...: In theory, calculating date of conception is just pure math. However, there's a range of probable vs possible dates given lifespan of egg & sperm. 2 calculators (http://goo.gl/ULNOoE & http://goo.gl/YKIZjS) included both March 31st & April 4th while 3rd (http://goo.gl/9pe8Oe) only included former. None of 3 stated that latter alone was date of conception w/o including former. Hope that makes sense

Do diapers have an expiration date?

Yes: But, it doesn't mean the product expires. Pampers says, "it doesn't mean the product expires...Paper products do not have a specific shelf life....We recommend our diapers be kept in a shaded, dry storage area where the temperature is 85 degrees or less. Extreme heat or humidity could effect their performance." they may change color, the glue get less sticky, gel may clump less as they get old.

How long do I need to wait to conceive after a miscarriage?

2 doctor answers3 doctors weighed in
Dr. David Fein
Specializes in Preventive Medicine
Three months: Most physicians will recommend at least three months, for multiple reasons. Whether a spontaneous miscarriage or having had a d&c, one desire is to have the cervix regain it's strength of closure for future pregnancies. Other beliefs are that the uterus has prepared the lining for a healthy pregnancy after a number of menstrual periods. The best answer is about 3 months.

Do doctors use the size of the baby to estimate the due date?

Dr. R. Wayne Inzer

Yes: Early in preg. Later, in the last trimester this is much less accurate. Once early dates are determined, they are not usually changed. Size later in preg can reflect genetics, nutrition, mothers health as well as baby's well being.

Mature baby: First question is when is the best time for fetal maturity. Second question is what is the safest time for mother and last question should be about convience for pt family or dr. Hopefully all can be safely met. Most drs. Agree, after 39 completed weeks.
A 21-year-old member asked:

What is the difference between use by and best before dates and why avoid foods that are out of date?

Reading food labels: "best before" typically refers to the preservation of optimal taste and texture of the food, while "use by" has more to do with its expiration. Expired foods run the risk of spoilage and bacterial contamination that make you sick when consumed.
