Hi Tasha,

I've been doing ivf for the last 6 months, so have no regular cycles atm, but prior to that my LP was about 16 or 17 days. ( ovulatated ~day 12, with a 29 day cycle) I got pregnant twice with a luteal phase like that, so I don't think it caused any problem with the getting pregnant side of things.

It is really hard to find any information about it, theres heaps on short LPs and how they can be a problem, but not much on what is a long LP and whether it means anything.

Don't know how helpful this is?

cheers, saffy x
