A 27-year-old female asked:

why would an ob change your due date from an ultra sound taken at 9 weeks of pregnancy but not mention until 3 days beore said due date?

Common: Bonnie, it is very common to revise the due date based on ultrasound evidence, because it is much more accurate than the first day of your last period. Why they didn't mention it earlier, I can't say, but remember that guessing a due date is an inexact science. Only 5% of babies are actually born on their due date. Hope this helps!

Yes: Usually after the first few weeks the pattern of stooling can change from after every feed to every two or three days, sometimes even longer. If the baby is urinating, gaining weight and is comfortable this is not a problem.

No: Generally, no. Pregnancy does cause sleep related problems, most notably due to discomfort and/or anxiety, and this can increase problems with depression. After delivery, sleep deprivation can add to this. Good mental health includes personal time, exercise and nutrition and deficiencies in any one do increase your risk.

Probably not: In younger women congestive dysmenorrhea can be very severe just before and the first 1-2 days of the cycle. If the symptoms are so severe consider using oral contraceptives which will relieve the symptoms. Talk to your gynecologist about it.
