weird cycles, please advise!

[FrizzyFrazzled]

DH and I are TTC our second baby.
Since going off the pill, I had one 21 day cycle and am now on day 27 of my current cycle. I am assuming going off the pill might have stuffed with my cycle a bit, making it 21 days one time, and that now it is back to 28 days. So I have not been allowing myself to get excited. Until now, of course, day 27 of my cycle, not having had any PMT symptoms... I know the advice will (obviously) be to TAKE A TEST, and I will, over the weekend, but I was just wondering if anyone knows whether my 21-day cycle would have been a one-off because off going off the pill, or not?

I came off the pill in aug and my cycles were really short to start with and noe they are getting longer (this one is getting on for 6 weeks) i have had lots of blood tests at the gp but they all seem to be coming back normal feel like i am not getting anywhere. good to know im not the only one buggerlugs good luck with your blood test hope hormones are ok !
