Hi Naru, I think Tamara's quote says it all. All bodies are different and hence all cycles are different.

How long is your lutal phase normally? And as Tamara said - Have you tested yet? Also do you know exactly when you ovulated?

I'd say that maybe if it's longer than normal to get a BT done to find out. You could be very early PG and can't be picked up on a HPT yet.

Good luck anyways.
Thanks for the answers. I only started temping this month, and according to Fertility Friend I'm 19 DPO. I'd say this is well over my last two LPs as the last two cycles were only 25 days in length. I've already done three tests (one before AF was due and two since) and all were negative.

I think I'll go to the doctor some time this week if AF doesn't arrive in the meantime.
