The National Women's Health Information Center lists these common causes of urinary tract infections in women: 1  Wiping from back to front after a bowel movement. 2  Having sex. 3  Holding urine for too long.  Being 1  diabetic. Having a kidney stone or other factor that makes it difficult to urinate.  Producing less estrogen, such as after menopause.
However, the estrogen hormones in Premarin Vaginal Cream may decrease the production and quality of breast milk. It is for this reason that estrogen-containing medications (including Premarin Vaginal Cream and many birth control pills) are not usually recommended for women who are breastfeeding.
WHO recommendations for breastfeeding. 1  Breastfeeding should begin within an hour after birth. 2  Breastfeeding should be on demand, day and night. 3  Bottles or dummies should be avoided. 4  Exclusive breastfeeding (only breast milk given-not even water consumed) should occur until the baby is 6 months.
