I'm not coggy, but I have a few thoughts on Luteal Phases (the time between OV and AF).
14 days is the "average", which means pretty much no woman actually gets there. If you have a luteal phase of less than 10 days it can be a barrier to conception (because even if you do fertilise an egg it doesn't have a chance to "bed in" before AF flushes it away.
Getting a +ve on an OV kit does NOT mean you are ovulating. Again, for most women it does, but an LH surge (which is what the kit measures) does not always result in OV.
When I started TTC one year ago, my initial temperature charts indicated that I had a luteal phase of just 7 days. I was also using OV kits, which were giving me +ves. After three months of that I went off to see my GP, expecting him to laugh at me and tell me to come back after a year. He didn't - he took me seriously and sent me for blood tests. These indicated low progesterone levels, and I got my referral to the fertility clinic.
My first appointment at the fertility clinic indicated that I was, despite all the signs, not ovulating. So I've been on the fertility drug, clomid, since then.
It's difficult to extend your luteal phase if it is short. I appeared to extend mine from 7 to 10 days by taking a vitamin B6 supplement (50 - 100 mg per day), but as it was later proved I was not ov-ing, this could mean nothing. Clomid is supposed to also help with your LP, by making you ov earlier in your cycle (and on clomid my ov day has moved from CD16/17 to CD14).
I recommend your friend discusses this with her GP.
Hope this helps!
