I was in the same situation as you not long ago, DD was 4 months old, I was expressing full time, we were DTD, not trying as such but no contraception (sp?) either. I had all of the typical signs of pregnancy and was almost convinced that I was pg, I did 2 HPT and they where both negative, about 7-10 days later AF reared her ugly head, it seemed that it was my body preparing for her return . It was a good thing though as we are now able to actually TTC knowing that I am ovulating.

Sorry back to you... it is possible that you could be pregnant (it has happened to woman before) although it is proberly not likely, I think that the HPT should be acurate if you do test.

Good Luck in getting the result you are hoping for
