Thanx BW! I spoke to my Clinic and they agreed I was ovulating earlier than the norm this month, but that this sort of thing starts to happen after age 35. But I have been spot-on with 28 days cycles since AF returned some months back. I was assured my lining was a good thickness. I think I might speak to my FS tomorrow after my next BT and see what he thinks, ie: would early ovulation during a natural FET cycle affect my chances of implantation...
