Please help with cycle and ovulation question

crzygirl

How do I determine how long my cycle is exactly?  I have been tracking the first day of my periods for the last several months.  I have been using an only baby center ovulation predictor.

 However I don't know if I am ovulating now or next week because I don't know how many days my cycle is. 

I don't want to go buy one of those expensive ovulation predictors at the store.  I was just hoping there was some calculation I can use.

 Any info would be greatly appreciated.

You need to either temp or buy OPK (ovulation tests) to know exactly..

For instance I have a 28 day cycle but always ovulate on cd17 so if we did it on cd 14 like web would say we would miss it..

Your cycle length is Day 1 of your period through Day 1 of your next period. So if you get your period on October 1st and your next period on October 29th, your cycle is 28 days long. The only way to know for sure when you ovulate is to chart.

If you really want to get informed and track this, go to www.fertilityfriend.com.  They help you use your CM and BBT to pinpoint your ovulation.

Thank you!  Some months it is 24 days and other months it is 26 days.

Agree with the pp. The only thing I would add is that your luteal phase (the phase between ovulating and the start of your period) will never be more than 18 days. So, if you consistently have a 28 day cycle, your ovulation date will never be before day 10 of your cycle. Or, if you consistently have a 40 day cycle, your o date will never be before day 22 of your cycle. (this is assumming, of course, that you are actually ovulating... which you won't know unless you temp)

I don't know if that helps or not - but it's another clue if you don't want to temp for some reason.

So if you're ovulating, you're doing it between cycle day 6 (very unlikely) and 16 (assuming you have at least a 10-day luteal phase).
