Ok first you need to relax a bit because it is the weekend and most the regulars dont get on during the weekends. Also you barely gave 30 minutes for people to reply. Not every one will be able to answer you.

Salt water shouldnt have any effect on your period. Chances are during the time you should have ovulated it was delayed hence delaying your period. Any number of things cna do that from a change in eating habits,stress,illness and so on.
Your best bet is to see your doctor since it has been so long between periods and get a check up done. Let your doctor know that this has happened before. So call your doctor in the morning and try to get in as soon as you can to get things checked out. Chances are he/she will run a series of hormone tests to make sure your hormones arent out of whack. Also just because you used a condom doesnt rule out pregnancy. All forms of birth control do have failure rates of some degree or another.
