I'm so glad I've found this site, there's a wealth of information here. Anyway, my luteal phase is only 10 days long according to my chart on fertility friend - I can't work out how to link to it to show you. I'm really concerned that this isn't long enough, is one month's cycle enough to go on or should I wait until a few more have passed before I approach my GP? I'm 39 and am worried about running out of time
