After urinate y my panties are getting wet even though I wipe with the toilet paper?

Terminal incontinenc. You need to see either your gynecologist or a urologist or both. Sounds like some pelvic relaxation has resulted in dribbling after you think your bladder has completely emptied. This may be due to your pregnancy, but you should get a professional opinion by somebody who can examined you. Best of luck and have a great baby.
