No Period?

[CaPagrl]

I am overdue and just wondering if it could be related to LC. Of course, I've done LC twice in the past and never had this happen, but this is so weird. I've been fairly regular since last March and I'm still breastfeeding my toddler (20 mos. old), but this is the first time since, maybe last August that I've been anything more than 2-3 days late. My LMP was 2/5/08. Today is 3/12/08. My cycle had been essentially every 31 days. So that would put me at 36 days, 5 days late. Maybe I shouldn't worry (maybe the worry is making it later), but I took yet another HPT this morning to make SURE I'm not pregnant and it was negative, so either I'm getting false negatives and we're going to be blessed next Thanksgiving-ish or my period's just gone a'missing!

Anyone have any thoughts/input/ideas on this? I supplement with CLA/GLA and a multi-vitamin (my prenatals, actually).
