I firmly belive that the only reliable 'symptom' at this stage is a rising HCG - dont stress about the other stuff - it will just do your head in (trust me on that one).

No two people (or even pregnancies) will have the same symptoms at the same time, our bodies react differently to the hormones being produced. I know how hard it is to hold onto the belief that you are still pg - I think I did a POAS at 11 weeks because I was not feeling any 'symptoms' (except being tired), and thought that it was all over!

In a week or twos time you can have an ultrasound which should pick up a heartbeat which can help to make it all that more beliveable! I know that it is impossible not to stress, but I hope that you are able to belive that you are still pg - symptoms or no symptoms...but if you are really in doubt, ask for another HCG test to put your mind at ease (at least for a few more days )

good luck
