What Determines When AF Comes Ovulation

Is it true that AF comes 14 days from when you ovulate? So because the first part of your cycle (pre O) can vary in length that is what makes it seem AF is late when in fact you actually Od later than you thought making AF due later than you think?? Unless you have a leutal phase defect ?

Kimberley, that is pretty much correct, from what I've read. Except that what they actually say is that your luteal phase remains constant for each woman, and is usually between 14-17 days long. So you have to track for a few months (with opk sticks or temps or something) so you know when you ovulate, and then when your period comes, and then you'll know how long your luteal phase is. Another thing that can make your period is late is when you have a cycle where you don't ovulate. Apparently it happens to most women once or twice a year, and can make your period late because it comes on because the lining has built up as much as it can and just needs to be released. That happened to me the first time I used opk's. I thought they hadn't worked because I never got a positive, and then my period was 9 days late (talk about torture!) but of course negative hpts. Whoops - I'm prattling on now, aren't I?! Good luck with ttc!! :-)

Thanks Lynette, I thought I had it all straight until someone freaked me out with the suggestion that I Od to late to sustain a pregnancy if I was lucky enough to get pregnant. I am on clomid and I have heard ALOT of women say that it made them O late but, no one had mentioned that it could cause problems. Thanks for the input!!

I think I know what they are referring to - I think if your luteal phase is 9 days or less there isn't enough time for the embryo to embed itself in the uterus wall. I haven't heard about that being a common thing to happen with Clomid, but I'm not on it so I can't say for sure. What I have heard a LOT of women say is that Clomid worked for them and they were successfully pregnant really soon - so I relax and I'm sure that will be true for you. Good luck again!

More good news for you Kimberley - I just did some "googling" and apparently Clomid is sometimes prescribed for people who have short luteal phase, so you definitely don't have to worry about that being a problem for you. :-)
