when to give up hope?

I'd suggest temping. If your temp was up higher than usual and your AF was overdue you could be pretty sure you were pregnant before even testing.

Your cycles can take a while to regulate after having a bub and b'feeding. I got my first AF back when DS2 was 6 months old and I didn't get another AF for 45 days (I used to have a 28 day cycle), I have not had a regular cycle since either!

Good luck

Similarly to Trish I got AF back at 5 weeks PP... then somethingg like 8, 12, 24 and now we're coming up on another 8 weeks with no AF. I'm still not pregnant despite her returning 10 days after i finished PP bleeding.
Sorry to say but I wouldnt hold your breath. Even when AF is back BFing can prevent implantation. *sigh*

Thanks for the replies, AF has returned - which is a relief, because now I can TTC again this cycle. I am planning on using opk's to see if I am even ovulating.

If this cycle doesn't work out I have decided that I am going to wean DS (I would probably do this soon anyway as he is a year old on NOV 7th, and I don't think I would bf much longer then that).
