Tictac i would recommend you start charting your temps and invest in some OPKs. also, sorry about TMI, but do you check for CM internally? lots of people can't find any unless they do that.

Good luck, the best way to have a boy is to DTD a lot around your fertile time.

As a general rule, the average luteal phase is around 14 days, so if you take that off the end of your cycle, that should give you a rough idea of when you are possibly going to O (and of course you're fertile for about 4 days before that).

Hope this helps!
