Breastfeeding and Short Luteal Phase

[lysh]

I always had a short luteal phase, even while conceiving my first. I had to take progesterone supplements. DH and I want to start TTC next month for number 2, I am still BFing (night weaned though, but nurses all day) and have gotten my period 4 times. This time I kept track of it, and realized my luteal phase is now 6 days!!! That is REALLY short. Anyone else have this issue while ttc and breastfeeding? What did you do?
