CD 28 – CD10/11 which would be 17-18 day luteal phase.  It’s the time between ovulation and menstruation and is usually 14 days and shouldn’t really fluctuate all that much.  Normal is 12-17 days.

Your luteal phase begins the day AFTER you ovulate.  It  typically remains the same – if you O’d on day 16 and you think your luteal phase 14 days. your cycle should be 30 days this month.  If you O’d on day 17, your cycle would be 31 days.  But, if you O’d on day 11 last month and had a 28 day cycle, it looks like your LP is 17 days.  If it is 17 days and you ovulated on day 16, then this month your cycle would be 34 days.

If you just went off the pill though then your body still may be regulating so you should expect to have some irregular cycles (ie, 28, then 34, then 32, then 30 etc).

Are you SURE that you ovulated during cycle 1?  Do you chart?  (If you don’t chart, then you can’t confirm O 100%.)  A 17-18 day LP is not necessarily porblematic, but it does seem really long.

@jholler25: As an FYI,

just because you get a positive on any ovulation detection method (the monitor, strips, smiley face digitals) does not mean that you in fact ovulated.  It simply means your body is gearing up to ovulate.

The only way to be 100% sure that ovulation happened, and thus be able to properly calculate your luteal phase, is to chart.  Charting your BBT and seeing a sustained shift in the later part of your cycle confirms you in fact did ovulate.

One thing to remember @jholler is that the CBE digital OPK measures only when you have an LH surge, not when you ovulate.  Did you continue to take OPKs after days 10 and 11?  I’m only learning this stuff too, but it does seem like a 17 day LP is longish and that it could be that you ultimately didn’t ovulate until later in the month.

Example – Last month, I had an LH surge at day 11 but don’t think I ovulated then (had no CM, no cramping and only had 1 positive morning OPK, then a negative OPK that afternoon) but then later in the month  did get CM and cramping followed by a positive CBE morning OPK on day 21 and then another positive OPK in the afternoon.  I don’t chart, but that’s when I think I ovulated.

@jholler25: Interesting about the first cycle post B.C. I’m on my second cycle post B.C. I’m approaching my second period, but felt what I think were ovulation symptoms a couple of weeks ago with really tender breasts. I think that was when I ovulated because right now I’m going through the typical pre menstrual symptoms. Here’s to hoping that Tuesday sticks with my cycle schedule.

@jholler25:  the CBEFM will ONLY tell you that your body “wants” to O, not that it did.  Sorry!  To confirm O, you need to chart.

If you don’t want to chart, you can use my *extremely* unscientific method…  The couple of days after I O I wake up sweating and incredibly hot – I can tell my temp has skyrocketed before I even take my temperature.

@jholler25: I use the CBEFM and my temp rises are often a week after the peak!  It’s frustrating and I don’t know if it’s because of my body not being regular or that the monitor is more inaccurate than I thought it would be.  At least you are getting a peak which is good.

That’s the trickiest thing about figuring out your LP!  You have to figure out when you ovulated!  Combining the monitor with temps has been really helpful for me.  But like a poster said above.  If you ovulate later, you should get AF later because your LP should be pretty constant (although mine still doesn’t seem to be! It’s 1-3 day range though).

I think as far as what to base your cycle on, use last month and the monitor together to help you predict, but the O date is a better predictor than the OPK or last month.
