I have late O and short LP, I usually O around day 16 and then get AF around day 26 but some cycles I O as late as day 22 and get AF on day 28. My progesterone levels are fine tho, or at least they were last time I had them checked.

Low progesterone is the most common cause of a short LP tho, whether or not that is a problem with TTC seems to be a bit disputed. My specialist said he didn't think LP defect was an issue when TTC and that research is really divided on whether it is or not, but I know it's common practise for women with LP defect to be prescribed progesterone supplements to help lengthen the LP.

Not sure if having just had a baby would affect your progesterone levels, but breastfeeding definitely does. Prolactin (one of the hormones involved in milk production) is what has a contraceptive effect when you are breastfeeding, and it can mean lower progesterone levels.]]> Sat, 15 Sep 2007 23:42:23 +0000 https://www.ohbaby.co.nz/forum/forum_posts.asp?TID=10759&PID=214102&title=progesterone#214102 https://www.ohbaby.co.nz/forum/forum_posts.asp?TID=10759&PID=214052&title=progesterone#214052 Author: Helen21

I don't think the lack of progesterone causes late Ov but it does cause AF to come sooner and make implantation more harder. This site might help you a bit.

Just wanting to get some more info on this. My cycles are regular but my O has been fairly late, with AF only about a week after. Jess suggested it could be low progesterone. Anyone know any more? Would that also be the cause of light/short AFs? Do people usually get low progesterone after having a baby?
