Thanks for writing in.
I suggest you should repeat a pregnancy
test if you are overdue for your periods for some time. As this test is, I would say inconclusive at this stage.
For your urinary problem; It may be just your vaginal secretions. If the problem persists you may go for urinalysis
I don't think you have ruptured anything. Try to drink a lot of water along with a diet rich in fruits & vegetables this will help with your constipation
