No it is not. The urethra is located higher up and right under the clitoris. The vaginal opening is closer to the anus and located inside the labia minora (inner lips).
The urinary opening is called the same thing no matter what your gender. The urethra is the tube that connects to the outside of the body.
The urethra is below the clitoris, but above the vaginal opening. See Link. http://adam.about.com/reports/Female-reproductive-anatomy.htm
Your menstrual flow comes out via your vaginal opening. The vaginal opening is at the bottom/back of your vulva, between your urethra (where you urinate from) and your anus (where you deficate from) - the vaginal opening is the same hole that vaginal discharge comes out of. Try looking at diaphragms online, such as from sex education sites like Scarleteen, to get an idea of where to look.
The vaginal opening is situated to the back of the vaginal folds, between the anus and the urethra. The urethra is the opening for urine to exit the body, it is the small opening in the center of the labial folds.

Although the urinary opening -- called the urethra -- is on the end of the penis males and above the vaginal opening in females, the urinary system has nothing whatsoever to do with the reproductive system. If urine has "pus" (which can only be confirm by microscopic lab testing), it generally means there is a urinary infection. A urinary infection does not affect fertility in any way, ever (unless the persons are too tired from the infection to be interested in sex!).

A Kegal exercise is an exercise to tone-up the vaginal muscles in order to prevent urinary incontinence, uterine prolapse, and improve vaginal sex. It involves flexing and relaxing the vaginal muscles - the same muscles used if you were to stop your flow of urine mid-flow.
The vulva (the outside) has 2 holes; the urethra and the vaginal canal. The vaginal canal (the inside) has one opening in the end and that is the cervix, the opening to the uterus.
The opening through which menstrual flow flows is the vaginal opening. Menstrual flow leaves the uterus via the cervix and then passes through the vaginal canal.
