This is my first, and it happens to me constantly. The worse is when I throw up, it's not a little tinkle, it's a full on pee. The throw up thing used to happen before I got pregnant, but back then it was a little tinkle. The joys of being pregnant. My doctor told me that kegels help, and I tried them for awhile, but they didn't... my mom and sister not have this issue, so I just figured I was destined to also lol.
