4 days late, BFN's..frustrated!

[Wish85]

So this is my first cycle ttc #2 and of course it's the ONLY time I ever have a screwy cycle! I am regular every 24/25 days but this month I am 3-4 days late but keep getting BFN's so I'm obviously not pregnant but I don't know why all of a sudden I'm late - the only other time I've ever been late was when pregnant with my son but I got a BFP the day after missed af.

I just wish my af would start now so that I can move on and start again! grrr, sorry ladies just venting really xx
