When your uterus puts pressure on your bladder, as it grows (also when your baby drops, close to delivery), you may experience mild incontinence and frequent urination or urinary problems.
It's fairly common, especially in the third trimester, to have trouble with leaking small amounts of urine when you sneeze or cough, often referred to as "stress incontinence".
By doing Kegel exercises, you can tighten and tone the muscles in your pelvis, which can help control incontinence. Wearing a panty liner or sanitary pad may make you feel more comfortable. By avoiding fluids right before bedtime can reduce your bathroom trips during the night, although make sure you are getting the recommended eight 8-ounce glasses of water during the day.
