Hi Ali,
The first time i got pregnant i knew straight away as i had really bad morning sickness and felt faint all the time, i felt shocking - unfortunately that pregnancy ended in miscarriage a couple of weeks later.
This time around I have had hardly any symptoms. My BB's are tender, i have to get up to the loo at least 3 or 4 times a night and some days my appetite is huge but apart from that nothing. I have had one or two days where i felt a little nauseaus but am thinking now maybe that was just all in my head?? I too was a little worried so went and got my HCG levels checked but everything seems to be fine - they are rising up nicely. When are you booked in for your first scan? I'm having one on Monday (8 weeks) and it can't come soon enough!!
I've done some research on the net and i have been finding more and more bits of information where is says that some people just don't get many symptoms at all - maybe we're just two of the lucky ones?
